The reaction is given by:  2 \mathrm{KMnO}_4+3 \mathrm{Na}_2 \mathrm{SO}_3+\mathrm{H}_2 \mathrm{O} \rightarrow 2 \mathrm{MnO}_2+3 \mathrm{Na}_2 \mathrm{SO}_4+2 \mathrm{KOH}

2 moles ofKMnO_{4} reacts with 3 moles of Na_{2}SO_{3} for reaction completion.

1 mole of Na_{2}SO_{3} will react with 2/3 mole of KMnO_{4}.

2 moles of Na_{2}SO_{3} will react with 4/3 mole ofKMnO_{4}
