Standardization of H2O2 by titration with sodium thiosulfate
« on: December 18, 2007, 10:56:08 AM »

If someone knows any link from where I can take the precise amounts of Na2S2O3, H2SO4, KI, starch as well as the exact formula for determination of H2O2,  from a sample that it suppose to have 30% concentration of H2O2, please send it to me.
Thx in advance for any useful answer regarding my problem.
