With the help of suitable examples,explain the property of $H_{2}O_{2}$ that is responsible for its bleaching action?
(N/A) The bleaching action of $H_{2}O_{2}$ is due to the release of nascent oxygen upon its decomposition.
$H_{2}O_{2} \longrightarrow H_{2}O + [O]$
The nascent oxygen $[O]$ is a strong oxidizing agent. It reacts with the colouring matter present in substances and oxidizes it to a colourless product.
$\text{Colouring matter} + [O] \longrightarrow \text{Colourless matter}$
Due to this oxidation property,$H_{2}O_{2}$ is used for bleaching delicate materials such as silk,wool,feathers,and ivory.
