Hydrogen peroxide solution
20 ml reacts quantitatively with a solution of
KMnO420 ml acidified with dilute
H2SO4. The same volume of the
KMnO4 solution is just decolourised by
10 mL of
MnSO4 in neutral medium simultaneously forming a dark brown precipitate of hydrated
MnO2. The brown precipitate is dissolved in
10 ml of
0.
2 M sodium oxalate under boiling condition in the presence of dilute
H2SO4. Write the balanced equations involved in the reactions and calculate the molarity of
H2O2.
