(A) HOCl + H2O2 → H3O+ + Cl− + O2 (B) I2 + H2O2 + 2OH− → 2I− + 2H2O + O2− Choose the correct option.

1. H2O2 acts as reducing and oxidising agent respectively in equation (A) and (B)
2. H2O2 acts as oxidising agent in equation (A) and (B)
3. H2O2 acts as reducing agent in equation (A) and (B)
4. H2O2 act as oxidizing and reducing agent respectively in equation (A) and (B)

Correct answer: H2O2 acts as oxidising agent in equation (A) and (B)

Solution

In both equations, H2O2 is responsible for the oxidation of other species, which means it is acting as an oxidizing agent. In equation (A), it oxidizes HOCl, and in equation (B), it oxidizes I2, confirming its role as an oxidizer in both reactions.
