Key Points
- The bleaching action of chlorine is an oxidation reaction.
- It requires moisture for its bleaching action. Chlorine reacts with water to form hydrochloric and hypochlorous acids.
- Cl2 + H2O ——→ HCl + HClO
- Hypochlorous acid is unstable, and it easily separates to form nascent oxygen.
- HClO ——→ HCl + [O]
- Nascent oxygen is the most powerful oxidising agent. Its formation is responsible for the bleaching nature of chlorine in the presence of moisture.
