Title: H2O2 concentration determination
Post by: Vesago on May 28, 2004, 03:58:00 PM

Does anyone know of a method for determining the H2O2% in solution?  Perhaps a titration?

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!

Title: Equimolar amounts?
Post by: Vesago on May 28, 2004, 05:05:00 PM

Do they react in equimolar amounts?

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

(methyl_ethyl: "Failed Peracid Oxidations? Check your H2O2 conc.!!", Newbee Forum) 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

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
