The other day I was reading about the German v2's. They added a tiny amount of hydrofluoric acid to the nitric acid to prevent the steel container from being attacked. One of my hobbies is blade forging. A big problem for me is corrosion. Stainless steel results in inferior blades, and you can hardly chrome a sword. I was wondering if I could apply this fluoride protection to my knives/swords. An iron fluoride layer sounds like it would make 'em just about invincible. Could it work? What concentration of acid should be used? Will it just passivate the iron, or will it eventually dissolve all the way through (stupid question). Will the protection be permanent? (practically…

Dear All, I AM NOT A CHEMICAL GUY. I want to make a cleaning cloth. I am from India and a businessman. I had seen in fair that one company was selling a cleaning cloth by dipping a cloth in a transperent gel. If I mix Ammonium Hydroperoxide and Hydrogen Peroxide, will it make a cleaning gel. If possible please reply email address removed

The definition my science booklet has for a base is a substance with an OH- ion. I told my teacher that I thought the definition in the book might have had limitations and he basically made me feel like a complete idiot. However, I thought ammonia was basic but NH3 doesn't have OH. I probably am wrong here, but could someone please explain to me why I'm wrong because I'm really confused. Is it only a base in solution or something? Because I thought it could react in gaseous form and operate as a base. As I'm fairly certain it's quite obvious, I don't really know a whole lot, so a little help and an explanation as to what I have done wrong would be really helpful. Thank yo…

I refuse to purchase expensive, branded household cleaning products. I have a gallon of bleach and a gallon of dish soap under the sink and that's all I really need. For general purpose kitchen cleaning, I have taken an old squirty bottle/trigger spray bottle in filled it with the green liquid dish soup, some bleach and than topped it of with water. The resulting mixture is green as one would expect due to the addition of gren coloured detergent. On inspecting the mixture after a few days, I've found that it has become completely clear; like water. No green at all. Even if I add more green liquid detergent, it still goes clear after a while. I know that bleach tends to…

Hey, as you've probably gotten from the really long title and much shorter description, this is going to be a series of experiments and creations in which I'm going to often ask questions because a lot of the information I want is difficult for me to find a condensed version of on the internet. Other than here. The first thing I want to do is mix battery acid and a powerful base in a container that the acid won't eat through, then evaluate it's byproducts, the reaction itself, and whatever else. A few quick questions. 1. How do I get battery acid from a battery? All that's available to me is alkaline, but I could possibly buy something else if that won't work. …

What makes a gas to be lesser soluble in warm/hot water than in colder one?

Can anyone give me some help on how I could effectively and efficiently make HCl ? Any help would be greatly appreciated, thank you.

I'm no scientist, but does anyone think it possible that there are chemical elements and chemistry in the universe not yet discovered by human science? I'm thinking about writing a sci-fi story about alien life. Most scientists describe life as being carbon-based, with the possibility of silicon-based life (this last is very much the province of sci-fi writers.) If there were other chemical elements as yet undiscovered, perhaps these too would be conducive to life, which would be of a very different form.

i repeat; if mixtures have properties of their constituents then why is steel not attracted by a magnet?

if a mixture has the properties of its constituents why is it not attracted by steel?

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)?

Well, I'm all out of KI after a recent nuclear war. Not seriously, I just used the last in an experiment. Does anyone know where I could get some more, and for a good price? I prefer to buy things at actual stores, but I'm willing enough to get it off the Internet. It doesn't have to be too pure, 98% would be very good. I've seen potassium bromide at pool stores, might they have it there? Any help would be very appreciated. And mods, yes, I know, anything involving iodine reeks of meth, but that's not what I'm trying to do. I'm making iron iodide for nonna yo bidness.

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'm reporting in to say that I just electrolyzed a solution of MnCl2 and successfully obtained a plating of pure manganese metal. The solution was very saturated, iron cathode and carbon anode about an inch and a half apart, and 2 amps of current was used if anyone wants to try this at home. Meanwhile, I'm going to go convert all my MnO2 to MnCl2... >;D Pics will follow if I get a large enough yield.

Hello, As an amateur element collector I have been given a few grams of elemental Calcium metal turnings. I know Ca is not as reactive as the Alkali metals so was hoping to store them in air, within a tightly closed small glass lidded container? Or is it common practice to store Ca under mineral oil? Advice would be very welcome. Many thanks, BF

I would like to know if anyone can give me a confirmation on the following: If you take stainless steel, dissolve it in concentrated HCl to get a green solution, and add excess alkali, the chromium will be the only thing left in solution because it forms a complex while nickel, iron, etc. do not. Is this true? I have a beaker of HCl eating away at the end of a SS fork as we speak, so if it's possible, I'd like to attempt it. The final product I'd like is chromium (III) oxide. And also, I'd like to avoid someone telling me "It's easier to buy your own". This is for the educational purposes, people!

When I've dissolved NIB magnets in HCl before, I ended up with a dark purple solution, as expected. But on this run, my solution turned a fairly dark green. Is this due to Fe2+ ions in solution? If so, what should I do with it to remove everything but the NdCl3? Some things I've seen are: -Solvent extraction by isopropyl and methyl-ethyl ketol I can do this, but I'd have to order the MEK. -Convert to sulfate, then solvent extraction in acetone I'm not sure this works, I read it on another science forum. -Precipitate out Nd(OH)3 by adding solution of NaOH, then reconvert to chloride This might precipitate out the Fe3+ ion as well, so not sure what to do here. …

I need a way to dissolve as much oxygen as I can in a saltwater solution. I was thinking of something with a tray full of saltwater on top with a tube leading to the vessel that needs the oxygen solution. The thing is, no electricity or pumps are allowed. The oxygen has to be from the air. No peroxide or bleach stuff.

I was thinking about ammonium fluoride recently, it's similarities to water. Anybody want to post some rumblings about it? What temperature does it decompose at, if it does? Could it exist as a liquid at atmospheric pressure? Would it make a good solvent for anything? How could I make it? Could I make it from ammonium chloride and something with fluorine? Any info appreciated, thanks!

I have some really dirty fe2o3, with little bits of grass and everything. To purify it, I thought I might dissolve it in hcl, to get as much iron chloride as I can in solution. Then I'd filter it to remove most of the contaminants. Next I'd add naoh or koh to make their respective chloride in solution, as well as an Fe(OH)3 precipitate. The Fe(OH)3 would be filtered out and rinsed several times to remove residual solubles. Then I'd dry out the stuff, and bake it into Fe2O3. Any suggestions? Improvements? Criticisms? Ramblings and equations about why it would/wouldn't work? I'll take 'em all. Thanks.

I'm officially out of fe2o3. Would anyone like to share their favorite method of making it?Btw, does anyone know the price per kg or pound for steel wool these days? (not stainless steel, and in us dollars please) Thanks for any help, my "pottery" is really being hindered by this.

It's the early hours of the morning and as usual I'm browsing alltime10s' YouTube channel. Botulinum is the most deadly by far out of all 10 listed, but then I read in the comments section something about 'nova 6', which is associated often with COD blackops. However, I am also told it is a real substance, but there's nothing really on the internet about it. Which is weird for the internet. Has anyone else heard of it who would care to give me a bit of history/information on it? Is it worse than botulinum toxin? From the small amount I've heard about it, it's horrible stuff. ^ If you know nothing of this maybe you can help me here instead: Mercury ranked i…

I was thinking about galvanic corrosion recently, and I got an idea. If you can increase the reacting surface area of a piece of iron by many times, you should be able to make it corrode very quickly, maybe even enough to boil water. You could start out with copper foil, or a foil of any metal lower than iron on the reactivity series. Get some trash cans or other large containers. Some copper wire, rubber tubing, gravel, water, and optionally salt will be needed as well. Cut out a lot (I'm really not exactly sure) of sheets of copper foil that will fit into your container. Take one sheet, and place it flat on the bottom of the container. Take a small handful of clean grav…

I have some sulphuric acid, supposedly 98%, that I bought as drain cleaner. Anyways, it is really muddy brown / black in color, and I think it might have an inhibitor of some sort to reduce its corrosiveness. How would I go about filtering the acid? I was thinking of using some sort of sand filter, but I can't think of a way to contain the sand and allow the acid to go through. Would anyone here with some pure, technical grade acid mind using a pipette to put a single drop on a piece of standard printer and timing how long it takes to start charring? Tell me the results of course. It will help me decide if it has any inhibitor, if it does, I'll just throw the stuff away.

Suppose I had a lot of limestone... Does anyone know how I would go about removing barium or strontium compounds from it? There should be some strontium and barium carbonate impurities in it, right?
