Perchloric acid + hydrogen peroxide... equation??


Need chemical equation for perchloric acid + hydrogen peroxide, for school no less this is what i think it is but it wont balance so it cant be right...

HClO4 + H2O2 --> HCl + H2O +H2?

someone shed some light?? :o




I would rather have a bottle in front of me, than a frontal labotamy...

As I recall, that reaction doesn't happen, at least at ~50% total concentration (that was about 70% perchloric with 30% H2O2, wasn't it?). Would be interesting if H-O-O-Cl(=O)3 (peroxyperchloric acid) formed.

Why would you get H2? Why would you even get HCl? You've got two rather strong oxidizers, and (with enough heat) you're going to get something like Cl2 + O2.

Probably gonna oxidize the H2O2 to oxygen.

I don't expect any reaction at all, unless pure waterfree reagents are used. In that case, the H2O2 may be protonated somewhat by the very strong acid HClO4, but that's all. The mix, however, will be an extremely dangerous mix. Any reductor (e.g. wood, dust, paper, metals, sulfites) can set this stuff off. On heating I expect to to become unstable and decompose explosively to water, O2, Cl2.

^^ well itsa good thing this is theoretical lol, but even so, none reactivity makes this very easy, but lets say it does react would these be possible solutions?

2HClO4 + H2O2 --> 2O(ClO4)2 + 2H2

or

2HClO4 + H2O2 --> 2OHClO4 + H2

i figure the hydrogen from H2O2 will form H2 but im not sure what compound the oxygen will form

Why do you insist on hydrogen forming? Hydrogen is a reducing agent, and a rather good one! Hydrogen and H2O2 do NOT exist together, I'm telling 'ya.

Peroxide will react under the right conditions to make peroxyperchloric acid, HOOClO3. It is not easy though. But since this is theoretical, it could be valid.

Interesting as a sidenote, I read that ClOClO3 exists. I bet it is fun stuff.

peroxyperchloric acid + nitryl chloride -> O2NOOClO3? Sorry... nasty compounds.

There are a ton of nasty F compounds, such as FNO3, FClO4, etc, where F has replaced H in the compound. Also, things like FOOF and FOOOF exist as well. They'd be fun if they didn't burn everything. Apparent FOOOF was mixed into liquid oxygen at ppm concentrations, and it caused fuels like kerosene to become hyperbolic (ignite when the fuel and oxidizer are mixed in the rocket motor).
