`SO_(2)` and `Cl_(2)` both are used as bleaching agent. What factors cause bleaching ?

Text Solution

Verified by Experts

`SO_(2) + 2H_(2)O rarr H_(2)SO_(4) + 2H`
`Cl_(2) + H_(2)O rarr 2HCl + O`
Bleaching action of `SO_(2)` is due to H (that causes reduction) and that of `Cl^(2)` is due to O (that causes oxidation)
