The reaction of

{H}_{2}{O}_{2}

with potassium permanganate in acidic medium leads to the formation of mainly

Options

A ${Mn}^{2 +}$
B ${Mn}^{4 +}$
C ${Mn}^{3 +}$
D ${Mn}^{6 +}$

Correct answer

A. ${Mn}^{2 +}$

Step-by-step solution

When hydrogen peroxide is treated with acidified potassium permanganate, the reduction of permanganate ion to ${Mn}^{2 +}$ ion takes place by the following reaction,
$2{KMnO}_{4} + 3{H}_{2}{SO}_{4} + 5{H}_{2}{O}_{2} \to {K}_{2}{SO}_{4} + 2{MnSO}_{4} + 8{H}_{2}O + 5{O}_{2}$
In the above reaction, potassium permanganate acts an oxidising agent.
