How does \[{{H}_{2}}{{O}_{2}}\] behave as a bleaching agent?

Answer:

The bleaching action of \[{{H}_{2}}{{O}_{2}}\] is due to its oxidising nature, i.e., due to nascent oxygen which if liberates on decomposition when it acts as an oxidising agent \[{{H}_{2}}{{O}_{2}}\to {{H}_{2}}O+O\] Coloured material + O \[\to \]Colourless Coloured material gets oxidised with nascent oxygen and oxidised form is colourless. \[{{H}_{2}}{{O}_{2}}\] bleaches delicate materials like silk, hair, ivory, cotton, wool, etc.
