Title: Standardization of H2O2 by titration with sodium thiosulfate
Post by: dana 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.
