Q8 / 90 · JEE Main 2022 (25 Jul Shift 1) · Chemistry

The reaction of $H_{2} O_{2}$ with potassium permanganate in acidic medium leads to the formation of mainly

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

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.

Hence, the correct answer is option: 'A'.
