H2O2 concentration determination
« on: May 28, 2004, 03:58:00 PM »
Does anyone know of a method for determining the H2O2% in solution?  Perhaps a titration?

Titrate with KMnO4

I would titrate it with a very dilute permanganate solution... Be careful though, as oxygen and water evolves violently if the concentration is too high!

Equimolar amounts?

Do they react in equimolar amounts?

KMnO4 + H2O2 -> K+ + MnO4- + H2 + O2  ?

might help,  ;)  

I should have used a different subject title to make it easier to find in TFSE.

If you would have input the terms hydrogen, peroxide and concentration into the search engine, you would have found

as well as others on the same subject  :P

Thanks for the "help", but I need a method that is accurate to a tenth of a percent.  For the record, I used The Fucking Search Engine, and I found that Fucking Thread, but it wasn't what I was looking for.

Methyl_Ethyl - thank you
