Hydrogen peroxide acts both as an oxidizing and as a reducing agent depending upon the nature of the reacting species. In which of the following cases acts as a reducing agent in acid medium?
Options:(select one or more)
Answer:
A, D
Solution:
(A) MnO₄⁻: Strong oxidising agent; H₂O₂ reduces it → acts as reducing agent
(B) SO₃²⁻: It is already a reducing agent; H₂O₂ oxidises it → not reducing
(C) KI: I⁻ is reducing; H₂O₂ oxidises it to I₂ → not reducing
(D) HOCl: Strong oxidising agent; H₂O₂ reduces it → reducing agent
