How does `H_(2)O_(2)` behave as a bleaching agent?

Text Solution

Verified by Experts

The bleaching action of `H_(2)O_(2)` is due to liberation of nascent oxygen on its decomposition
`H_(2)O_(2)toH_(2)O+O`
The nascent oxygen oxidises the coloured material to colourless products. This bleaches their colour.
Coloured material + O `to` Colourless
Thus, the bleaching action of `H_(2)O_(2)` is due to the oxidation of the coloured material by nascent oxygen. It is used to bleach silk, hair, wool, ivory, cotton, etc.

SO_2 acts as a bleaching agent. How?

Hydrogen peroxide is a powerful oxidising agent, both in the acidic and alkaline medium. In acidic medium: H_(2)O_(2)+2H^(o+)+2e^(ɵ)to2H_(2)O In alkaline medium: H_(2)O_(2)+2e^(ɵ)to2overset(Theta)(O)H Hydrogen peroxide acts as a reducing agent towards powerful oxidising agents. In acidic medium: H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ) In alkaline medium, however, its reducing nature is more effective. H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ) H_2O_2 behaves as a bleaching agent due to
