Give reason for the bleaching action of `Cl_(2)`.

1.	Give reason for the bleaching action of `Cl_(2)`.
Answer» Bleaching by chlorine occurs in the presence of moisture. In fact, it releases nascent oxygen on reacting with `H_(2)O` which carries bleaching. Since the reaction cannot be reversed, the bleaching by chlorine is permanent. `Cl_(2)+H_(2)O to 2HCl+underset(("Nascent"))(O)`
