In my opinion, you can't work hard unless your job is one of intense physical labor. Sure, you might have an important job. Do a lot of stuff. But work hard? Nah. Falling into bed after 19 hours of straight tobacco labor is "a hard day's work." Not falling into bed after a 10-hour shift in an air-conditioned office. I would never consider anything you could possibly do as "hard work."

 

Do you, by your own definition, work hard? Does more than 5% of America? If the answer to either of these questions is no, I suggest you come up with a better argument.

 

Ooooooooooooo. I am so GLAD you said this. So we've already cleared the fact that my father works hard, right? So, according to you, my quality of life would've improved and I would've gotten opportunities because of his hard work, right? Did that happen? Nope. Your quality of life would have improved if he had managed to acquire enough money to make it. Hard work does not always lead to succes. Cunning and hard work lead to success. Seeing how you are above average, I would guess your father had cunning, but lacked luck/opportunities. Seems like the odds weren't in your favor.

 

My father instilled a work ethic in me that allowed me to have a solid GPA in high school. I scored incredibly high on the administered standardized tests in every section, particularly the mathematics and sciences. According to you, I should have had opportunity-palooza! But I didn't. The scholarships I was offered only covered tuition. My family couldn't afford to pay the rest. They couldn't shell out money for books, a laptop, meal plan, etc, because they were below the poverty level. I wasn't going to school.

 

Enter the government: I was offered Pell Grants, state financial aid, and federal aid accorded to me due to my background from living in a very impoverished region *and* being a minority. And other wonderful measures thanks to "dirty socialism" that the conservatives are now so Hell-bent on repealing. I could finally attend college. Who said I disapprove of financial aid for promising students? This is an investment in America's future, and one with a very good return.

 

 

 

My father certainly tried. But it wasn't enough. Luckily for me, the government stepped in and ensured that I would be able to attend uni and receive a physics degree. And, thanks to their further intervention, grad school awaits in the future.

 

Sometimes, it doesn't matter how hard a person works. Sometimes, all the cards are stacked against them. Sometimes, people just need to be helped up from the dirt. This is the simple logic no conservative seems to understand. Are you seriously trying to say I don't help people? I volunteer time, give food to the poor, help build at habitat for humanity, help troubled kids, help the boyscouts. Help kids with schoolwork. Help old people cross the street. Hold doors for everyone. I go completely out of my way to help people, but because I am a republican, people assume I am a prejudiced, hateful, bigot, who couldn't miss an opportunity to look down on someone. I am almost the most charitable person I know.

 

Um, you were arguing that American workers expect to be paid much more than the man in hong kong. Don't you think this has a lot to do with the differences between our costs of living? How would our businesses survive selling products at US prices if our people make Chinese wages? You're pulling from only one side of the equation and then claiming we're overpaid.

Americans aren't overpaid, the Chinese are underpaid. In this day, who could think we're overpaid? Except for the occasional billionaire, of course. So many people need our help.

 

I'm guessing these are Chinese people who've moved to the US, correct? People who are earning US wages, have the wherewithal to move halfway around the world and start a new life here? Perhaps you should meet people who actually live in China before you make such comparisons.

People who moved to the US, and in Hong Kong. Admittedly, I've never been to mainland China (except to refuel), but the people in HK seemed to be very hard workers. Is it different in mainland?

We relaxed banking regulations and look what happened. Regulation isn't always a bad thing. Business complains because that's what the model calls for, and they can make even more money for shareholders if they get to cut corners with our health and safety, especially when it's made legal through deregulation. This isn't as cut and dried as most Republicans think. It can be extremely dangerous in the long term to relax good regulations. Regulation is always needed, of course, but in moderation and in the right places.

 

This is why I'm proud to pay taxes that help Americans better themselves, rather than helping already successful businesses pay their executives and stockholders more. Free market capitalism already gets to use my roads, schools, airports, libraries and other public projects, plus I support them with my consumerism. If they can't succeed with that much, they don't deserve to succeed.

My father used to work 120 hours a week on the family farm so that it wouldn't go under. He turned down an electrical engineering job offer from IBM because of his sense of duty to his family.

 

I doubt you've ever done true, backbreaking physical labor like the kind I was raised around. So do not preach to people about what true labor is. You do not know. And yes, I do know that for certain. I can tell by the arrogance of your posts and how dismissive you are of the plight of the less fortunate. You are cold and elitist.

If people were paid for the amount of work they actually did, my family would be worth billions of dollars thanks to my father. We are not. We are still technically classified at the "below poverty" level for a family of five.

 

Your posts reek of a complete misunderstanding of life and what low-income work actually is. Quite frankly, it's nauseating.

 

I don't have a physical job, admittedly. But where's the shame in that? Nowadays, very few Americans have physical jobs. The key words in your post are "that I was raised around". All of my family came from such a background, starting as poor farmers, and gradually increasing their children's quality of life, education, and job. Now, after this hard work has paid off, I have been given a life full of opportunities, and a college education. One day, I will pass on an even better life to my offspring, and they shall have a higher quality of life than I did. My family as well has had it's hardships. I respect you, for knowing the troubles of life. In essence, we are the same. Your chain of events just hasn't progressed as far as my own. I knew low income work, btw, before I went to college. I had to work quite a bit for what I have.

 

I will flat out guarantee it's the same way in China. I agree. Just to a lesser extent.

 

 

As I mentioned before, the Chinese cost of living is much less, so they need less money to live. Consumer prices in the US are over 42% higher than in China. Rent for comparable housing is over 52% higher in the US. Restaurant prices are over 85% higher in the US. Source: http://www.numbeo.co...2=United+States

But they can buy much less, either way, even including the differences in cost. The Chinese cost of living is low because they have no more money to spend to increase that cost. I can guarantee you that if they made more money their cost of living would increase.

And it's a fairy tale that Chinese people all work hard. Lazy is a human trait, and you'll find it all over the world. Of course there are some lazy people, but I have met only 1 or 2 lazy Chinese people, and a whole hoard of admirably hard working ones.

 

 

Romney wants to give corporations even bigger tax breaks. And they're already sitting on record amounts of cash, and have the highest paid C-level executives of all time. Aren't they doing well enough that maybe they can pay the same rates they were back when the US was super prosperous? Businesses need consumers to be able to afford their products, after all.

We do need to give businesses less breaks. But with these reductions in breaks should come reductions in regulation. I am all for giving businesses breaks, however, if we can make them spend it here as a condition, to benefit the American people, and have some way to enforce this. American tax dollars need to benefit American citizens.

 

They already have a bunch of doors that will do that, and would be more efficient at ventilation, and provide better security than so many windows being openable. I'm not saying I think mitt had a good idea, I'm just saying that with a few modifications it isn't a completely retarded idea.

 

 

I was shooting for ironic. CaptainPanic is from Niederlande.

Oohhh... Sorry, I thought you were mocking me. It's been done before. Not by you, of course.

It WAS meaningful to me. That IS the real problem, we aren't doing enough to learn where we're wrong, where we're being inefficient, where we could do better. And I like that you can recognize when public funds should go to the public welfare. I was born an Eisenhower Republican and I hate how the party has let itself be so degraded by extremist conservatives. I was born into an independent family, and I became a republican because I found their views were most similar to my own. I am not an extremist conservative. I am not a political lemming. I make my choices based on rational thought. Not bias, or hate.

 

 

 

 

How do you ensure that, and at what cost? Why would you need to open the windows, anyway?

 

I'll leave that to the engineers. I don't think mitt's was a good idea, I'm just trying to point out that, with modification, it isn't completely retarded. To let in oxygen of course. Lol

I also believe that the gold nanoparticles can not release ions. But the question is that I can not explain to myself the toxic effects. Some authors have demonstrated that the toxicity of the gold nanoparticles is due to their interaction with the proteins of lysosomes. So cell death is given by the blockade of vesicular trafficking (Quantitative Evaluation of Cellular Uptake and Trafficking of Plain and Polyethylene Glycol-Coated Gold Nanoparticles, Small 2010)

The lysosome has an internal pH of 4.0-4.5, can allow the ionization of gold?

Yet another question concerns the output of gold ions from the lysosome. The biological membrane is permeable to gold ions?

Thank you all for your help.

 

Ph isn't always what makes something corrosive. But corrosive things often have an extreme ph. Why does aqua regia, but not perchloric acid dissolve gold? Perchloric is the stronger acid. I find it difficult to believe something organic with a ph of 4 could ionize gold. But I would like to be proven wrong. The toxicity is pretty much a mystery to me. If you knew what the other component of the ionic substance was, it would make this a much easier problem to solve. Unless you think you have pure gold ions. lol

A window that's a square foot in area, or 144 square inches, has a pressure across it of , say 10 psi. That's a force of 1440 lbs. With the mechanical advantage of 2, that's "only" a force of 720 lbs that your "small" latch has to hold. Plus a safety margin. If you open it at altitude, it's going to be quite violent.

 

Buses don't have these issues of differential pressure and the possibility of hypoxia and hypothermia if you open a window. Besides, a plane has emergency exits in addition to the main door. There's typically one one each side (over the wings) and an exit in the rear. Like a bus does.

 

Again, they should only open at a safe pressure level, and when the plane isn't in flight.

 

http://www.politico....al-problem.html

 

 

Well, if you'd respond to my points, that would be the beginning of the discussion you've been missing.

 

 

 

Yeah, CaptainPanic, why can't we just drop the whole political discussion thing, pretend it makes no difference and respect each other as Americans? Why? Why?!

 

Don't be mean phi.

 

It's especially important to have a progressive tax rate in light of the corporate personhood movement. Corporations are extremely necessary as an instrument for building commerce, but we can't allow them to enjoy the benefits of the general citizenry while simultaneously having the privilege to do business as an artificial entity and the freedom from general partnership liability. We all have to take the good with the bad, but this current crop of Republicans wants just the good, and they don't care who they take the extra good from or who gets all their bad.

 

This is simply a matter of businesspeople stacking the deck in their favor simply because they have the money to influence the way the laws get written. To say someone deserves to screw other people because they're wealthy is ludicrous. And to even think they got where they are without anyone's help is irresponsible and ungrateful in the extreme. To quote chilled_flourine, "This is a huge problem, admittedly, but we aren't doing anything to resolve it."

That's the first time I've been quoted on this forum... And it wasn't even meaningful. I'll give you a plus one.

So, according to your logic, slaves are the biggest bastards, because they pay no tax (no income, no tax). And the millionaires are the nicest people, because they pay the most tax.

 

Weird logic.

 

It may be off topic a little bit, but did you know that most European countries have a progressive tax system? Higher income means you pay more tax. Our highest percentage is nearly 50%, and some propose to lift it to 60%. So, multi-millionaires will pay over half their income in tax.

 

Why is that good? Because they're rich enough as it is.

 

This is yet another thing that I really don't understand about Republicans. Some of the republican voters are quite poor, yet they defend the regressive tax system as if it's beneficial to them.

Slaves are not bastards! Slaves are people who were taken advantage of, sold by their own people. I don't think you fully understand what I meant. I agree with you about the poor republicans, it is certainly not always in their best interest. But I won't refuse any support for my political views. Our ideas about politics are just about as different as they can get, unless one of us becomes a communist. There will be no swaying either of us to the other's views. I suggest we just do what Americans have always done (or are supposed to do), accept each others ideas and respect each other as Americans. Can we get back on topic? About the windows?

 

Since you refuse to use the quote system correctly, this is the only part of your post I can respond to properly. I do want to say though that progressive taxation makes sure that those who profit most from our infrastructure pay the most for it. How many of the 47% do you think use airports? Does the guy who works three jobs to keep his family fed plan a lot of road trips, considering he gets around on the bus?

 

American workers don't work hard? Wow, that's a fairly elitist, heavily biased and incredibly naive statement. We have an extremely robust cost of living, it costs us a lot to buy products here, as opposed to what they pay for the basics in Hong Kong. I understand the benefits of arbitrage when applied to labor costs, but I'm talking about demanding US tax breaks so corporations can create US jobs to help the US economy and then using that revenue held back from public funds to create foreign jobs. Do you thinks that's good business for the US? Do you see why our economy is in trouble due to this withholding tax revenue and profoundly unhelpful efforts to help themselves instead of the American workers that helped them build those businesses?

 

 

Wow, that sounds just like it came from someone's dad. Have you been in the workforce long?

I'm glad you said almost.

 

I have no problem with employing foreign workers. Again, that's not what this is about. I'm talking about tax revenue that was supposed to go towards helping US employment that went overseas instead, to help US corporations make more than half their profits overseas while enjoying tax breaks and charter exemptions they could only get from the US government, which is paid for in the majority, last time I checked, by US citizens, all of them.

 

I have been in the workforce for quite a while, and have worked hard all my life. Many Americans work very hard, but some don't. The thing is, Chinese people are raised to work even harder, and for much less money. I agree, it's stupid to give businesses our taxes to spend overseas.

Several authors in various papers attribute the toxic effects of nanomaterials to the release of ions from the main nanostructure (nanoparticles, nanorods, etc.). This is easy to perceive in the case of metal oxides and in the case of metals such as silver (1st Ionization energy of silver: 731.0 kJ·mol⁻¹). About gold? Why gold nanoparticles induces toxic effects in living cells? It is possible that gold ions are released by gold nanoparticles (1st Ionization energy of gold: 890.1 kJ·mol⁻¹)?

 

Gold ions? I dunno... Doesn't sound to likely. You'd need something pretty reactive to go about getting gold ions...

I'll buy that. If we could also eliminate campaign funding it would help. It's hard to think about these guys spending a billion dollars and not being obligated to SOMEONE. Media time and ad space should be part of the requirements for chartered use of the radio and TV frequencies as well as the internet and paper media. I'm sure there's some kind of government compliance for cable and satellite TV as well. Let's leverage some integrity.

 

 

How does a security-conscious Republican justify the safety threat of being able to open an airplane window? Who needs a bomb when you can just flip a small latch?

Read another one of my comments and you should see that I specified it would only open when the plane wasn't moving, and at a safe outside pressure. I'm not that stupid. I don't know how this would be accomplished, but that's not my job, figuring this stuff out.

 

It makes the people who still insist on taking his meaning out of context idiots, imo.

I don't take his meaning out of context. I know what he said.

How does a pro-War-on-Drugs, tough-on-crime Republican justify giving smugglers a way to toss contraband out the windows to bypass Customs and TSA? Or were you hoping to privatize a few more prisons and add to the US corner on the world's prisoners market? How exactly would you get illicits on a plane in the first place? Anything they failed to find the first time wouldn't likely be picked up on the second time around. There would be a sensor, that would only allow the window to open during a fire. Perhaps a gallium or indalloy seal around a detector, depending on the cabin temp.

 

 

 

 

They do? Romney's effective tax rate last year was 14.1%. Mine over the summer was 17.7%. He pays less than those on minimum wage who don't pay income tax. Yes, Romney pays less than that evil 47% he slandered.

 

He pays much more than the 47%! You are thinking of this as a percentage. I am thinking of # of $ paid.In what world is a few thousand greater than a few million? 100% of 0 is still 0.

 

The numbers disagree with you.See above.

 

 

Except the bit where minimum wage workers pay a higher percentage of their income to taxes than Romney. But, screw it, who needs facts? You're thinking percent, I'm thinking $. That is, btw, how millionaires got so rich, thinking $ .

 

Oh, and lets not forget about him wanting to pay even less of his fair share and make the poor pay even more of a percentage of their income. He already pays more than is fair. I think it's generous how much more money he is giving than the average citizen.

 

Ooh, I wonder what the numbers are when sales tax is added in. Mitt still paying more.

 

 

 

 

In 1958, corporate taxes accounted for 27% of the total revenue. Today, they account for less than 9%. When we extended the Bush tax cuts for the wealthy in 2010 because they argued that they would be able create more jobs, the wealthy created only one job for an American for every three jobs they created for foreign workers. And the top 200 companies in the US made 60% of their revenue in the last two years from foreign industry. Yet you say you support stronger immigration laws and are pro-business.

 

Don't you think a business that enjoys an American corporate charter should be more interested in helping the US economy? Especially when they're using tax revenue that should have gone to the public coffers to hire foreign workers? I'm pro-business too but I think they have an obligation to do more to support the economy of their charter nation. Isn't that part of the Republican platform too? It was when I was born.

The problem is, American workers expect to be paid much more than the man in hong kong, yet the American doesn't work as hard. See the problem? We need to teach our children to be hard, productive workers, and then maybe the millionaires will have reason to hire them. If you were a millionaire, I can almost guarantee you would hire the Chinese guy. This is a huge problem, admittedly, but we aren't doing anything to resolve it.

 

No, because most of us have the ability to understand the meaning of a phrase when listening to it in context.

 

Millionaires pay for their share of the infrastructure with taxes. They pay for more than their fair share with taxes. They just know how to get what they pay for. Millionaires probably payed for hundreds of times more of the road they ship their products on than the average citizen. Since everyone contributed (except the 47%), everyone gets to use it as much as they want. Even the 47%. To use infrastructure is a very basic right. What would America be without it?

We're talking rolling, not swinging. Even if we are talking swinging, that would only work if the hinge is on one end of the window. When's the last time you saw a vehicular window that swings which has the hinge on the edge of the glass?

 

 

 

 

Quite a bit so, actually. Although, I'm not sure if it's more idiotic than someone repeating that quotemine after being corrected several times. Oh, by the way, Romney said the same thing about Olympic athletes.

People do what works for a specific purpose. It doesn't matter if it isn't commonly done.

Only for a window that swung out. But for one that swung in, or rolled down, you'd be fighting the effect of the better part of one atmosphere of pressure differential. And because of the tendency to want to swing out, you probably wouldn't design it to open that way.

 

That's why you would put a small latch on the bottom. A window that swung inwards would be very hard to open, and it would give the people inside less space to escape any hypothetical danger. The doors swing out on emergency exits in school buses. There has to be a reason they chose to make them swing out.

 

Would it then not make more sense to vote for a republican senate and house of representatives, but still vote for Obama because he is not an idiot?

 

You do have a separate vote for the president, don't you?

 

What baffles me is that republicans knowingly vote for a complete idiot, just because he's the only republican on the list of options.

 

You didn't build that doesn't make Obama an idiot? I don't vote for republicans just because they are republicans, but because they express my views the best. I would gladly deviate from the platform, if someone was a better candidate in my eyes. For example, in 2008, I voted for a 3rd party candidate. Obama does not express my views, and McCain was a nut. If he won, we would be at war with Vietnam again.

I do think windows on a plane would be a great idea. So long as they only open above a safe pressure level, and while the plane isn't moving. Plus some other safety features.

Not at all. You're obviously not a religious right Republican. Are you a neo-conservative Republican? Or a Reagan Republican? An Eisenhower Republican? You meet so few Republicans these days that endorse scientific efforts, so I'm curious where you stand on the platform.

 

I'm right on the center of the platform. I enjoy thrashing Obama. I want the affordable healthcare act repealed. Pro life, pro gun, pro business. Stronger immigration and voter laws. I know what the meaning of marriage is. You name it. I'm just one of few republicans who knows quackery when they see it. "The greatest enemy of knowledge is not ignorance, but illusion of knowledge (ie the catholic church)." Can you seriously expect any sane person to believe the earth is only 5000 years old, when carbon dating, continental drift, dinosaurs (apparently Noah forgot them), and evolution, all of which are highly proven things, tell us otherwise? I have seen evolution go on in a kennel, my garden even. Disprove that. Can you expect us to believe it when you say that everything scientists say is one big lie, sent from satan, when everything from the projector on your church wall to the polyester of your shirt was designed by one? Can you expect us to read a book so riddled with inconsistencies it's apparent even to my 15 year old nephew, then expect us to find rationale in your saying "it's not meant to be read as a novel"? The meaning of the bible is only truly found when one reads it for what it is, a work of fiction, and cover to cover. I don't deny the possibility of a god existing, only that the one/s described by current religions seem highly unlikely, and their holy books severely flawed. Perhaps you could become a deist, like myself. You can say you believe in god. You can fit in with Christians, while avoiding the bad things that come with lack of acceptance. Deists believe an intelligent creator started everything, then left it alone. Or, alternatively, this creator planned everything perfectly, and the universe is following this deity's plan as we speak. Even this, I don't believe in as sincerely as I could.

I doubt (depending on the altitude, of course) that Romney could even open an airplane window if it did roll down.

 

Really? Positive pressure on the inside, near vacuum on the outside. Isn't it common sense that the window would very willingly swing into the low pressure zone?

I find myself unable to believe mitt could say something as stupid as this. Almost as bad as bitter people clinging to guns and religion. You might have guessed I'm a republican. We have to give him some credit. A good 95% of the people out there would have believed him, if relatively knowledgable people like ourselves weren't out here to criticize him. But these ARE the things you expect the president to know.

If you wish to remove mercury from sodium, distillation is your best option. Mercury boils at 357 C, while sodium boils much higher at 883 C. A good hotplate can easily achieve 360 C, and a ground-glass setup would probably help. Plus, you get your mercury back!

 

I've only seen boiling mercury once, and even now, it makes me nervous just thinking about it.Yes, you CAN make sodium! I've done it myself. I would know.

I've had my own experiences with heated H2O2... not fun.

However, that was at about 300 C on a stoveplate, and I had no clue about the dangers.

95-99 C wouldn't boil the water, it would basically evaporate it at an elevated rate. If you're worried, lower the temperature: This slows things down while being safer in terms of sudden decomposition.

I've had to wait for months for certain topics to get replied to... In fact I just received a reply email a few days ago, about a query I had sent over a year ago. Things like this happen...

 

Again, sorry. I've noticed that at that temp, at least 50% of it decomps. in the time it takes to do any useful concentrating. I miss when 55% was EASILY available, before 9/11. Damn terrorists. Now I can hardly buy anything more dangerous than bleach, without being put on a watch list. Ironically enough, it is very easy to make explosives from bleach... Maybe it'll become the new ammonium nitrate, ridiculously regulated.

Hf and CaCO3, hmm? It would work, but if I had to make some, I'd prefer using NaF and CaCl2 to avoid... well... the obvious. And because the only place for me to get NaF is the same place where I can obtain CaF2, why bother?

Darn. Iridium's good stuff, I have to use sparkplugs (infinitesimal amounts, high price. Joy.)

Added! And might I say that I'm not quite as uneducated on the dangers of chemistry as most college students. Which isn't much to claim, considering what I've seen at my school so far.

 

 

 

 

 

College... So fun, so dangerous. Fun is directly proportional to danger, ya know?

If you're not too afraid, add in 30% hydrogen peroxide until you get a 4:1 hcl to h2o2 ratio. This is MUCH more corrosive, the hcl will dissolve any oxides that might be formed. I got a big piece of SS to dissolve in less than 10 minutes. Piraña bath is much more effective, if you like metal sulphates. It's the same, at least conceptually, but much more dangerous. Stay safe.

I urgently need 20+ grams of urea nitrate, at least 90% pure. Could someone please post links to a few types of fertilizer that meet these specs.? Any help would be VERY much appreciated. I live in southeast US, sorry uk people, but this isn't really for you. If you think you have any info though, by all means, I'll take it.

I found out recently that Have been dating a pathalogical liar. If you do not know what this is, read carefully: it is someone who fabricates nearly everything in their lives, briliantly, almost undetectably. It is very scary and I am realizing, now, that I developed arthritis in my fingers between the 2nd and 3rd dates with this person.

 

The though occurred to me that perhaps he drugged my food and somehow this has caused the crippling of my hands.

 

I could see someone of thi nature carrying something like this out bc once I would find out who he"really" is (much less 'adequate' in his own eyes than the millionaire, ebonaire perosn he made himself out to be), I would be less likely to leave bc I would need him.

 

I know poisoning doesn't usually involve symptoms of arthritis...but one never knows.

I'd love any feedback or experience, strength and hope.

Thank you!

I don't know of any toxin that could induce arthritis like symptoms, except maybe HF. But there would be more noticeable things before what you described. Go to a doctor. If you have any evidence whatsoever, go to the police. I really have to say that you are probably just getting paranoid, and nothing happened. It's either nothing, or you actually have arthritis,

Darn. Just got my ignition mix today, but college has started as well. Will also have to find some CaF2. This might be delayed a little longer.

 

To make caf2, get yourself a hunk of limestone, and a certain type of rust stain remover. Dissolve with excess carbonate, filter, then boil down. The stuff has a tiny bit of srf2, but they work the same for flux purposes, and it really is a negligible amount. Oh, don't breath the fumes. But you knew that, didn't you?

Sorry I refuse to tell where I get my iridium, but I need every last bit of it.

 

Darn. Just got my ignition mix today, but college has started as well. Will also have to find some CaF2. This might be delayed a little longer.

 

I'm not entirely sure I feel comfortable talking about thermite with a college student. Btw, now that we have spent so much time rambling together, I feel obliged to make ye a formal friend request. I'll add you if you add me. Mkay?

Topic died. I hear a better, more efficient way is to place some 3% on a hotplate and heat it to 99 C (just under boiling). After a few hours, it'll evaporate right down to a good concentration.

I'm afraid it will decomp. on me. Bad experience with 55% once... No one was hurt, lucky thing. I don't know why it took me so long to realize you had replied.

Thanks for the reply. Glassblowing and creating an Ampoule are not options at the moment! Besides, a big part of my interest in Element collecting is to actually see, feel and handle the material in its raw form, so i would like to store it in as assessable way as possible. (when i eventually get hold of 10g of pure Au, i will throw the packaging and certificate away!)

 

I just want to know if it would be safe to store Ca carefully in a small jar without mineral oil.

 

 

Many thanks,

 

BF

Well, personally, I ampoule all my alkalis and alkalines, as well as my uranium and other reactive stuff. My glassblowing skills are quite good. And I have lots of test tubes... I always flush my tubes with neon first, I had an incident with a rather thin walled tube where all the air inside was consumed, a near vacuum was created, and the thing burst. Neon stops that problem. Argon and helium are also fine. Lighter than air gases create an entirely new problem, however (flying containers of liquid caesium, lol). I hate having that greasy juice all over my good metal, and it's hard to get it off without exposing to air or water. Acetone works okay for cleaning, but then you have to get the acetone off. Of course you can safely store it in a small mineral oil jar! Really, why not? Remember, eventually air can and will diffuse into the oil, causing corrosion to the metal. This is more of a problem for the extremely active elements, such as caesium and rubidium. Even then it would take years to be noticeable. An inert gas is the best way to go. Go ahead though, use your mineral oil. It'll work more than good enough. Just remember to keep the lid airtight, or make a double airlock of sorts. I'm sad, I ran out of rubidium

 

Surprisingly enough, yes. For a few years at least. I had some lumps of Ca myself, and I kept them in their original plastic container (not filled with argon or anything) for about half a year, and they were just as shiny as ever. The main thing is to keep them dry and safe from reactive gases. Eventually, I ampouled my Ca anyway.

Now, turnings could be somewhat more reactive than lumps, so a tight container with not much air space is recommended until you get an ampoule and a good torch or Bunsen burner. Good ampoules can be made from disposable glass pipettes. Be careful, though: Molten glass is not friendly. Use gloves and eye protection, and wear long clothing to avoid being burned too badly. If you're worried about your turnings, yes, I would store them in oil too. But mineral oil, at least in my case, has the annoying tendency to escape its container and give the surface an oily film. So, wrap it in a paper towel or something, and keep the vial upright.

 

10 g of pure Au? That's a fairly large amount. Where's it coming from (and who's paying for it)?

I get my au from thrift shops. I just dissolve and refine. I managed to get 50 grams after refining for about as many dollars.

Again, you very lucky person.

And where, pray tell, do you find your hoard of iridium?

 

I would tell you where I get my iridium, but they are currently out of stock and I plan on buying them up again when they get more. Having a rich relative also has downsides you know.

No, they'd rather no one corrected the misinformation they've been repeating, so they call it flaming.

 

I think you misunderstood me. I was poking fun at a certain resident expert...

 

Well, anyway...

If it's stainless steel, I'd expect the chromium to oxidize if the Fe did. Then, chromium (III) oxide reacts with strong NaOH to form hexavalent sodium chromate, Na2CrO4, which is soluble in water and has a bright yellow color.

I use a pretty standard Dewalt cordless drill, with a bit size of 17/64.

Malformed? How so? It works fine for me. If you wouldn't mind a search on YouTube, the title is "How to concentrate Hydrogen Peroxide from 3% to ~30%", by TheChemlife.

McLendon's is a hardware store in the Northwest U.S. area.

Force drying is using the Force to generate heat to dry a solid.

But seriously, it's another name for 'heating things on a stove, hoping they don't conflagrate and just dry normally".

I typically use ceramic plates for this sort of thing.

...Platinum-plated bowl?! You are an incredibly lucky person. No, a long dead relative was an incredibly rich person. She disliked silver, for whatever reason (ironically enough, the plating is on silver). That thing really does come in handy sometimes. I was thinking of making an iridium plated one, once I hoard enough iridium to make the plating solution. That thing would be nearly invincible. Until you scratch it of course, but considering how hard ir is, not too likely. I would say I'm about half way there. Iridium can be SO hard to find.

You know how it is when someone's wrong on the internet. They get flamed by certain grumps? :shifty eyes:

 

I was a TBH fan as a kid but not for Buddy. Partly for Irene Ryan who played Granny Clampett (OMG she was hilarious), mostly for Ellie May (any scene with her down by the "cement pond" was a hit with teenage boys).

 

Mkay.

H2O2? What does it do, get catalyzed back into water and oxygen? Or does the wool oxidize? With 3% it bubbles vigorously, making heat and rust. With 30% it bubbles VERY vigorously and catches on fire (if any is still dry).Oh, I've got to try that. Free chromium oxide if I boil the rust in NaOH, too. How would you get chromium oxide from it? Stainless steel wool maybe? How would you separate the cr from the Fe? Does cr have some soluble hydroxide I don't know about? I don't think stainless steel would be reactive enough to catch fire, but it would certainly oxidize in the 30%. My wool was plain Fe.

Just tried the magnesium + drill today, and HOLY SNAP, that's a lot of shavings. I got a container very loosely half-full of these things, and they get bigger the longer you drill. I only drilled in a few spots, too, and the holes produced were very shallow. I might have to try this with aluminum... > Mg is easier to shave, in my experience. Don't expect it to be as easy with al.

Darn. Still, the thing was a huge success. Even if the aluminum is harder, it should still work pretty well if it's pure.

What kind of drill and bit do you use? At how many RPM? I've never had much success with al, I usually make from foil or buy the stuff.

Al poisoning? I heard it was a neurotoxin, but not to what extent. Also, the exposure rate of aluminum in our everyday life is massive, from aluminum antiperspirant to aluminum cookware and much more. Admittedly, powder has some risks of its own, but the Wiki throw for 'health concerns' mostly speaks about how nontoxic it appears to be. The original actor for the "tin man" in the wizard of oz film almost died after using al powder to color his skin like "tin". He failed his entire career because of it.Well that's certainly... interesting... says nothing about that on the Wiki page. Really? I thought I saw it there as well while hunting for errors.

 

Should I physically dry the NaNO3? I have it with sodium hydroxide dessicant as we speak, with little action on the dessicant's part except for clumping together. If I recall correctly, there really isn't enough difference in hygroscopicity to make naoh an effective desiccant for nano3. Try a stronger desiccant, like sodium oxide or calcium oxide (both very dangerous). I still have to reccomend heating the stuff. After all, anhydrous sodium nitrate is much cheaper than sodium or calcium oxide. You could make the latter at home, however. This completely random, but have you ever tried to cut a piece of caesium metal? It's ridiculously soft. About as soft as butter, I would say. Any info about the h2o2?Or what about heating in a beaker on a stove? Force-drying. Microwave, even. I'm just afraid it might catch on fire...As for the H2O2, not really. I haven't found the time, sorry. Also, the McLendon's site doesn't have a product list or search engine, so the only way to find out if that concentrate even exists is to actually visit the store.

Might I suggest this video, if you have a hotplate:

It appears the URL you gave is malformed. Heating on a stove is heating, so yes. What is force drying? I'm always afraid to put things in the microwave, bad memories of mother catching something on fire... Ammonium nitrate, that I can see you worrying about, but sodium nitrate has no reducing agent, so why worry? Just don't do it in a metal bowl, unless you have a fancy platinum plated one like me. And if you do have a metal bowl, you'll probably make sparks, and therefore ozone and NOx. Lead might not spark, im not sure though. Please don't inconvenience yourself for me. I've never even heard of the store you mentioned, so purchasing it there would probably not be an option. Check out united nuclear's drierite, it works wonderfully.

This is getting a little cluttered, want to go back to the conventional way of posting?

 

 

 

 

The original guy ended up playing Jed Clampett, the patriarch of The Beverly Hillbillies, one of the most successful and highly rated TV sitcoms of all time.

 

Well, it appears I was wrong. The point was really that aluminium can be harmful. But I was wrong.
