The amount of H2O2 in 15.8g of hair bleach was determined by titration with a standard potassium permagnate soln.MnO4-(aq)+H2O2(aq)--Mn2+(aq)+O2
1. What is the mass percent of H2O2 in the sample if43.2ml of a0.105M KMnO4 soln is needed for the titration of the sample?
2. What is the reducing agent in the redox reaction?
