# How does H2O2 behave as a bleaching agent

9.35  How does H2O2 behave as a bleaching agent?

Hydrogen peroxide $(H_{2}O_{2})$  act as an oxidizing agent in basic as well as the acidic medium. In the exposure of light, it decomposes and gives nascent oxygen which combines with coloring matter which in turn gets oxidized. So the bleaching action of $(H_{2}O_{2})$ is mainly due to the oxidation of coloring matter.
