With the help of suitable examples, explain the property of H_{2}O_{2} that is responsible for its bleaching action?

Answers (1)

H_{2}O_{2} serves as a great bleaching agent and disinfectant, commercially sold as perhydrol and disintegrates on exposure to direct light.

The bleaching action of H2O2 is due to labile oxygen which it releases on decomposition.

H2O→ H2O+[O]

The nascent oxygen combines with coloured material and makes it colourless. It can bleach feather, silk, wool, paper, etc.
