Hydrogen peroxide solution (20 mL) reacts quantitatively with a solution of KMnO_(4) (20mL) acidified with dilute of H_(2)SO_(4). The same volume of the 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 precipitate 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).
