Hydrogen peroxide solution (20 ml) reacts quantitatively with a solution of KMnO

_{4}solution is just decolourised by 10 ml of MnSO_{4}in neutral medium simultaneously forming a dark brown precipitate of hydrated MnO_{2}. The brown precipitated is dissolved in 10 ml of 0.2 M sodium oxalate under boiling condition in the presence of dilute H_{2}SO_{4}. Write the balanced equations involved in the reactions and calculate the molarity of H_{2}O_{2}.3
