Explain what is the concentration of hydrogen peroxide

Reference no: EM13523440

A 5.0 ml aqueous sample containing hydrogen peroxide was diluted to 25 mL and analyzed by titration with permanganate.
MnO4- + H2O2 -> O2 + Mn2+ (need to balance this in acidic solution)

The sample required 42.8 mL of 0.0175 M permanganate to reach the end point. What is the concentration of hydrogen peroxide in the original sample?
