Bleaching action of chlorine is by
A
oxidation
B
reduction
C
hydrolysis
D
decomposition
Explanation: 

Detailed explanation-1: -Detailed Solution. The correct answer is Oxidation. The bleaching action of chlorine is an oxidation reaction.

Detailed explanation-2: -Chlorine bleaches are oxidizing agents; when chlorine reacts with water, it produces hydrochloric acid and atomic oxygen. The oxygen reacts easily with the chromophores to remove electrons from the molecule, chemically changing the structure of the molecule and the physical properties that cause the color are changed.

Detailed explanation-3: -Oxidising and bleaching action : Chlorine is a strong oxidising and bleaching agent because of the nascent oxygen. Colouring matter + Nascent oxygen → Colourless oxidation product. The bleaching of chlorine is permanent . It oxidises ferrous salts to ferric, sulphites to sulphates and hydrogen sulphide to sulphur.
