Hydrogen peroxide solution (20mL) reacts quantitatively with a solution of KMnO4. (20mL) acidified with dilute H2SO4. The same volume of the KMnO4 solution is just decolourised by 10mL of MnSO4 in neutral medium simultaneously forming a dark brown precipitate of hydrated MnO2. The brown ppt. is dissolved in 10mL of 0.2M sadium oxelate under boiling condition in the presence of dilute H2SO4. Write the balanced equations involved in the reactions and calculate the molarity of H2O2.
