Question

A 0.846 M KMnO₄ solution was used to determine the hydrogen peroxide (H₂O₂, MM = 34.016) content in a 25.48 mL of peroxide solution. It took 13.28 mL of the KMnO₄ solution to reach the endpoint. What is the percentage (w/v) of H₂O₂ in the sample?

The reaction is:

5 H₂O₂ + 2 MnO₄^- + 6 H⁺ ⟶ 5 O₂ + 2 Mn²⁺ + 8 H₂O
