Aqueous solutions containing approximately 3 percent(w/w) H2O2are sold in drug stores as a disinfectant. Determination of theactual concentration of H2O2 in a bottle of peroxide solution wasdone by diluting 1.00 mL to 100 mL with water, acidifying withdilute H2SO4 and titrating with a 0.01231 M KMnO4 solution. If41.92 mL of the permangate solution was needed to reach the endpoint of the titration, what is the actual molar concentration ofthe H2O2 solution? Hint: Balance the reaction first: MnO4 - + H2O2-> Mn2+ + O2 using half reactions
