Question

Chemistry

How does H2O2 behave as a bleaching agent. Explain with reaction.

Answer 1

It act as a strong oxidising agent both in acidic and basic media. When it added to cloth it break the chemical Bond of the chromoPhores. Hence the visible light not absorbed and the cloth get whitened

Answer 2

$Here\:is\:ur\:Answer$

H2O2 or hydrogen peroxide acts as a strong oxidizing agent both in acidic and basic media. When added to a cloth, it breaks the chemical bonds of the chromophores (colour producing agents).Thus the bleaching action of H2O2 is due to the oxidation of colouring matter by nascent oxygen.
