Question

The bleaching properties of ${\mathrm{H}}_2{\mathrm{O}}_2$ are due to its?

• A. Acidic nature
• B. Basic nature
• C. Oxidising nature
• D. Reducing nature

Answer 1

The correct option is C

Oxidising nature

Explanation for the correct option:

Option(C):Oxidising nature

• The bleaching action of any substance is defined as the process in which when a particular substance is added to the chromophore-containing complexes, and helps in the breaking of the chemical bonds in the solution by releasing the color of the material through oxidation.
• ${\mathrm{H}}_2{\mathrm{O}}_2$ usually acts as a good bleaching agent, which is due to the reason that when it is added to a cloth or any material which has coloration on it, it breaks the chemical bonds of the chromophores.
• Thus, the bleaching action of $$H_2{O}_2$$can be explained by the fact that it acts as a strong oxidizing agent both in acidic and basic media and hence oxidizes coloring matter by the release of nascent Oxygen.
• The reaction that takes place in the Hydrogen peroxide can be shown as:
  $\underset{\left(\mathrm{Hydrogen}\mathrm{peroxide}\right)}{{\mathrm{H}}_2{\mathrm{O}}_2}\to \underset{\left(\mathrm{Water}\right)}{{\mathrm{H}}_2\mathrm{O}}+\underset{\left(\mathrm{nascent}\mathrm{Oxygen}\right)}{\left[\mathrm{O}\right]}$

Explanation for the incorrect option:

Option(A):Acidic nature

• The bleaching properties of ${\mathrm{H}}_2{\mathrm{O}}_2$ are not explained due to its Acidic nature.
• Hence, the given option is the incorrect one.

Option(B):Basic nature

• The Basic nature does not explain the bleaching properties of ${\mathrm{H}}_2{\mathrm{O}}_2$ .
• Thus the given option does not represent the correct option.

Option(D):Reducing nature

• The bleaching properties of ${\mathrm{H}}_2{\mathrm{O}}_2$ are not explained due to its Reducing nature.
• Hence, the given option does not coincide with the correct option.

Hence, the bleaching properties of ${\mathrm{H}}_2{\mathrm{O}}_2$ are due to its Oxidising nature.
