H2o2

Recommended Posts

What would happen if you reacted H2O2 (not very concentrated) with nickel or palladium? Would there be an explosion?

iirc, silver mesh is a particularly good catalyst.

the bell jet pack ran on 99% H2O2, pumped it through a catalyst then through the nossles.

common commercial concentrations are about 3% or 9%.

nothing quite so volatile as to be called explosive.

at best, you're going to get a little fizzle of steam and oxygen.

Thanks! I am a student teacher and I wanted to complete a demonstration using a heterogenous catalyst. I wasn't sure if this would be safe or not.

I just did silver and Ni in H2O2 (9%) I think your students would get bored :)

Ni didn`t do anything and Ag was not much better (I have no Pd to try).

if you have a death wish, it is possible to distill h2o2 into jet pack quality stuff.

if you toss silver oxide gauze in that, you'll get a very large steam explosion. however, you get much the same effect if you hold a match to it (decomposition chain reaction)

KI is actually a quite spectacular catalyst for h2o2 break down and if you add a dash of dish washing soap and do it in and Erlenmeyer flask its called “Elephant Tooth Paste” for obvious reasons.
