Question

How does H2O2 behave as a bleaching agent?

Solution 1

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). Hence, the visible light is not absorbed and the cloth gets whitened.

Solution 2

Bleaching action of H2O2 is due to the oxidation of colouring matter by nascent oxygen.

H2O2(Z) ———> H2O(Z) + O(g)

  Is there an error in this question or solution?
