Overall Change in Oxidation State of Manganese in the Reaction
- When potassium permanganate (KMnO4) oxidizes thiosulphate (S2O3^2-) to sulphate (SO4^2-), the oxidation state of manganese changes from +7 in KMnO4 to +2 in Mn^2+.
- The oxidation state of manganese decreases from +7 to +2, resulting in a change of 5 units.
Therefore, the overall change in the oxidation state of manganese in the reaction is 5.
