Inorganic Chemistry

Ok I am going to begin this post as I do every one; I do not know that much about science or chemistry although I am very interesting i dont have much knowledge. So what i want to make is a liquid that glows in the dark or at least looks sweet as hell under a black light. I've seen powders that dissolve into paint and stuff to make it glow in the dark but the only problem with those is that the specific way we thought of having glow in the dark liquids is having a food coloring we could add to drinks to make them glow. So now the questio is are there any phosphors that are non-toxic and if not are there any food colorings that would react to a blacklight (dont think n…

Can anyone help me understand what is goin on in the reaction. KMnO4 + H2SO4 ----> HMnO4 + K2SO4 Or would the KMno4 just go in solution. when u touch anything organic to it it ignited and lets off a purple smoke what is it? Thanks

Hello, I want to know the color of the different elements when exposed to hight temperature. By the moment I´m interested on the mix of Mg Al O, and how it can change depending on the % of each element.

As many of you may know, I collect minerals. Recently, I bought a book that describes mineral tests with Cobalt Nitrate. Any ideas of how I could make it?

ok, i want to get some rusk. so i get a nail , connect to my 12 volt power supply. then i stick the positive and negative ends into some salt water ( tap water + cooking salt) first i get a layer of orange precipitate forming at the bottom( common rust) . but then i get a layer of green/white precipitate???? wat the hell is this??? i have heard that come iron oxide goes strangr colours but i want to conform that its rust. or it another oxide from the other composite in the nail???? any one got any ideas wa happening here?

A few questions.. I know you can make H2SO4 from SO3 and water and that it is dangerous, i wanted to find out how to make the SO3 form (sulfur) if it is possible, I know that this has been brought up before i just wanted a more in depth explanation on how to make SO3 and why its so hard. Also could anyone please tell me the products of this equation i get a bunch of different things for some reason? Na2O5S2 + H2O2 --->

Hi i was wondering why when you drop mentos or anything similar into a fizzy drink it fizzes?

Here is a description of an experiment, which I did with the preparatoin and detonation of silver acetylide. This is a very nice experiment, but one has to be careful. This explosive is not suitable for high volume preparation. The cost of it is very high (it is based on silver ), but in small quantities it shown interesting properties. If you have the chems, it definitely is worth yo try this, and it can be done safely, if the safety guidelines, given on the webpage are followed: http://woelen.scheikunde.net/science/chem/exps/silveracetylide/index.html

i have a bottle of antacid with Aluminum hydroxide and magnesium hydroxide, i wanna try to extract the aluminum hydroxide from the antacid, if it is even possible to do, it had other inacive ingredients in the antacid, any ideas on how this can be done?

Hi, I would like to produce a small flame, perhaps about the size of a golf ball or a little smaller, by burning hydrogen and oxygen. I understand that electrolysis of water can be done more efficiently by adding something like sodium sulfate to increase the conductivity. I need to know if it is feasible to electrolyze enough water into H2 and O2 to produce the size of flame I need (well, actually two flames this size) given the power I can get out of a wall outlet. Please let me know the required voltage and amperage and I can figure out what kind of transformer/rectification is necessary (is DC really needed if I am just going to be mixing the two gases, or can I ho…

Hi, i was wondering if anything like aluminium foil/tin foil (is that the same thing?) reacted with ammonia to produce a gas?

Hi, im a keen (thats not how its spelt is it?) chemist, and am trying to obtain nitric acid, of any concentration, as long as it dosnt have to many impurities, other than internet sourced products, what else is it in, ive heard about it being used ot etch copper, and in drain opners, but anyothers? anyhelp would be much appreciated

AFAIK the addition of dilute ammonia to metal(II) hexaaqua ions will always result in a hydrolysis reaction resulting in the hydroxide precipitiating, while ammonia in excess will result in an ammine complex. However when I was looking up ligand substitution reactions for iron(II) ions, I found that with excess ammonia the hydroxide forms and not the ammine complex. Does anyone know why this is? I would have expected all metal (II) ions to react in the same way.

yesterday morning I made a saturated soln of Sodium Iodide by dissolving NaOH and Iodine crystals in hot deionised water, the exact amount was "titrated" using solid media to leave a clear soln of NaI. upon cooling overnight Crystals have started to form. now in my books NaI is listed as being a Cubic crystal, and yet these I have here are quite clearly monoclinic! any Idea what`s goin on?

In chemistry, the cation is the positive electrode and the anion is the negative electrode. So far so good. Why has physics changed these around? In Geissler tubes the anion is now positive and the cation is now negative. Why isnt there a convention for charges?

This is only my 2nd thread in the chemistry section, and I have a simple question for the bright chemists out there(you know who you are;) ). Why do transition metals not form carbonates. I know it is roughly to do witht heir charge density and polarising power but I know there is a much more concise answer to this question. Thanks in advance:-)

My compound is an acidic compound. It is soluble in water. I need to extract it in Chloroform. Do i need to basify it so that it goes in choloroform? Archie

The other day I managed to salvage about 4-5 kilos of magnsium sulphate that was going to be thrown out. Anyway i'm at a complete loss as to what to do with them and I need some ideas. My only idea was to use them as a drying agents but i'm sure there is something more interesting I can do. Any ideas?

The drain cleaner i bought is mixed with some sort of charcoal like substance. Any ideas of a good filter that wont be completely attacked by the sulfuric acid. Thanks, Doug

I have done a lot of experimenting last two weeks with all kinds of halates and have investigated how fast they react, when mixed in a pyrotechnic mixture. I have access to the following ones: potassium chlorate, KClO3 potassium perchlorate, KClO4 sodium perchlorate, NaClO4 potassium bromate, KBrO3 potassium iodate, KIO3 potassium metaperiodate, KIO4 sodium metaperiodate, NaIO4 Of one of these (KIO4) I have made high speed movies with a digital camera, see thread http://www.scienceforums.net/forums/showthread.php?t=20936 . What I have observed is the following order of reactiveness with red P. KBrO3 > KClO3 >> KIO4 ≈ KClO4 >> KIO3…

Hello. I'm new to this seemingly awesome forum. So if i take a nitrate salt and put it in H2SO4 it will yield HNO3? Will this occur just by dropping (slowly inserting, solution of nit. salt maybe, since the acid is so exothermic) the salt into the acid? Will they react on their own? Of course I'd also set up an ice bath. When it comes to sulfuric acid, can liquid fire drain cleaner be used, in terms of purity? It says it contains concentrated sulfuric acid, and it gives all the wonderful warnings about how it can erupt violently from the drain anytime etc. so i thought id verify this. I get the impression that HNO3 is violently poisonus, but a whole lot …

Hi everyone. Recently reading a topic that was asking how you would make Hydrogen Cyanide (Among other things) and of corse there was no reply as I would have expected.

Hi I'm a new user here with some basic chemistry, If u encounter some bad english well sorry thats all i've got Here is what I did I have a table salt that contains normal salt (NaCl), dextrose, potasium iodide, sodium bicarbonate, yellow prussiate of soda. I've poured some of it in water (not sure of the quantity but it's 2:2) I've taken four 1.5v batteries and connect them together with to pieces of iron. Then i've put the two pieces in water (I was expecting to get NaOH cuz i didn't know that the salt conatains potasium and other stuff) the water started bubbling it turned to yellow there is some color less gas comming out (i think it's c…

One of the final issues that I am trying to resolve is the KNO3 for the nitric acid. The sulfuric i can pick up in 12M quantities at lowes. The idea is to make everything from ingredients available at common stores, so ebay or pre-purified KNO3 are not what I'm looking for. I was thinking saltpetre if I can find it. I read that it is around 94% KNO3 and I was wondering how I could purify it; would simply heating it in water, decanting, and filtering work? I don't think it should be dangerous at all, if I'm not mistaken KNO3 doesn't melt until up in the 300's ©. As always, the help is appreciated. -Doug

I have recently acquired about 1/4 of a pound of Cr2O3 from a rock shop. I have heard that it dissolves in H2SO4 to form a solution that gives Cr upon electrolysis. However, I cannot seem to dissolve it. Are there any chemicals other than H2SO4 and Cr2O3 that are needed? :confused:
