Question

$H_2{O}_2+H_{2}O\to H_3{O}^{+}+H{O}_2^{-}$

The reaction indicates:

• A. $H_2{O}_2$ is a bleaching agent
• B. $H_{2}O$ is more acidic than $H_2{O}_2$
• C. $H_2{O}_2$ is more acidic than $H_{2}O$
• D. both $H_2{O}_2$ and $H_{2}O$ are acidic

Answer 1

The correct option is C $H_2{O}_2$ is more acidic than $H_{2}O$

$H_{2}O$ is acting as a base in the above reaction as it accepts the proton. Thus, in presence of $H_2{O}_2$, water acts as a base and hence, hydrogen peroxide is more acidic.
