Explanation:

Hydrogen peroxide (H2O2) acts as a reducing agent when added to a solution of potassium permanganate (KMnO4) acidified with sulfuric acid (H2SO4).
- When hydrogen peroxide is added to the acidic solution of potassium permanganate, it undergoes oxidation, losing electrons and causing the reduction of potassium permanganate.
- In this reaction, hydrogen peroxide is oxidized to water, and potassium permanganate is reduced to manganese dioxide (MnO2).
- The overall reaction can be represented as follows:
2KMnO4 + 3H2SO4 + 5H2O2 → K2SO4 + 2MnSO4 + 5O2 + 8H2O
Therefore, in the presence of sulfuric acid, hydrogen peroxide acts as a reducing agent by causing the reduction of potassium permanganate.

In this reaction hydrogen peroxide acts as a reducing agent and it reduces KMnO4 to Mn2+ ions.
Potassium permanganate is used as an oxidizing agent to determine the hydrogen peroxide amount in a solution. Hydrogen peroxide reduces the permanganate to a colorless product.
