Question

Which of the following statements is incorrect for hydrogen peroxide?

• A. It is stored in plastic bottles in dark
• B. It acts as an oxidising as well as a reducing agent
• C. It is used as a bleaching agent
• D. It has acidic as well as basic properties

Answer 1

The correct option is D It has acidic as well as basic properties

Hydrogen peroxide $\left(H_2{O}_2\right)$ is stored in plastic bottles in the dark to prevent its oxidation by light. It acts as an oxidising as well as a reducing agent. Besides, it also has bleaching property.

However, $H_2{O}_2$ shows only acidic behaviour.

$H_2{O}_2\rightleftharpoons H^{+}+H{O}_2^{-};H_2{O}_2\rightleftharpoons 2H^{+}+O_2^{2-}$

$2NaOH+H_2{O}_2\to N{a}_2{O}_2+2H_{2}O$
