The reaction of H 2 O 2 with potassium permanganate in acidic medium leads to the formation of mainly

Options

  1. AMn 2 +
  2. BMn 4 +
  3. CMn 3 +
  4. DMn 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 → K 2 SO 4 + 2 MnSO 4 + 8 H 2 O + 5 O 2 In the above reaction, potassium permanganate acts an oxidising agent.
