An acidic solution of hydrogen peroxide behaves as an oxidising as well as reducing agent. Illustrate it with the help of a chemical equation.

This is a short answer type question as classified in NCERT Exemplar

(i) Oxidising action in acidic medium:

2Fe²⁺ (aq)+2H⁺ (aq)+H₂O₂ (aq) → 2Fe³⁺ (aq)+2H₂O (l)

PbS (s)+4H₂O₂ (aq) → PbSO₄ (s)+4H₂O (l)

(ii) Reducing action in acidic medium:

2MnO₄^-+6H⁺+5H₂O₂ → 2Mn²⁺+8H₂O+5O₂

HOCl+H₂O₂ → H₃O⁺+Cl^-+H₂O
