       H2O2 concentration determination     

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  ?

       Hydrogen Peroxide Concentration     

Post 461708 (methyl_ethyl: "Failed Peracid Oxidations? Check your H2O2 conc.!!", Newbee Forum) might help, wink

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

       Use the Fucking Search Engine !!!!     

If you would have input the terms hydrogen, peroxide and concentration into the search engine, you would have found Post 243407 (lugh: "Hydrogen Peroxide Concentrations/Density", Novel Discourse) as well as others on the same subject tongue

       Uhh...     

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
