Question:

Give the reason for bleaching action of Cl2.

Answer:

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
