Assertion : chlorine gas bleaches the articles permanently
Reason: chlorine is a strong reducing agent
Dear student,
The bleaching action of chlorine is based on oxidation. When chlorine reacts with water, it produces nascent oxygen. This nascent oxygen then combines with the coloured substances present in the organic matter to oxide them into colourless substances.
Cl2 + H2O 2HCl + [O]
Coloured substances + [O] → Oxidized colourless substance
Hence, it can act as an oxidizing and bleaching agent and it causes permanent bleaching.
Therefore, the assertion is correct but the reason is incorrect.
The correct option is C.
