Question : The bleaching action of chlorine is due to which reaction?
Option 1: Oxidation
Option 2: Hydrolysis
Option 3: Redox
Option 4: Decomposition
Correct Answer: Oxidation
Solution : The correct option is Oxidation.
The bleaching action of chlorine is an oxidation reaction, as it initiates the release of nascent oxygen when it reacts with the water. Oxidation is the gain of oxygen. Hydrochloric and hypochlorous acids are formed when chlorine combines with water. Because it is unstable, hypochlorous acid readily separates to produce nascent oxygen.
