MCQ

In acid solution, the reaction $MnO_4^ - \, \to \,M{n^{2 + }}$ involves

A
Oxidation by $3$ electrons
B
Reduction by $ 3 $ electrons
C
Oxidation by $5 $ electrons
✓
Reduction by $5$ electrons

✓

Answer

Correct option: D.

Reduction by $5$ electrons

(d)$MnO_4^ - \to M{n^{2 + }}$. In this reaction $5{e^ - }$are needed for the reduction of $M{n^{2 + }}$ as:$MnO_4^ - + 5{e^ - } \to M{n^{2 + }}$.
