Question
Give the reason for bleaching action of $Cl_2.$
✓
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.
$\text{Cl}_2+\text{H}_2\text{O}\rightarrow2\text{HCl}+[\text{O}]$
Coloured substances + [O] → Oxidized colourless substance.
