Question

The chemical nature of hydrogen peroxide is :

• A. Oxidising and reducing agent in acidic medium, but not in basic medium.
• B. Oxidising and reducing agent in both acidic and basic medium
• C. Reducing agent in basic medium, but not in acidic medium
• D. Oxidising agent in acidic medium, but not in basic medium.

Answer 1

The correct option is B Oxidising and reducing agent in both acidic and basic medium

$H_2{O}_2$ act as oxidising agent and reducing agent in acidic medium as well as basic mediumm.

$H_2{O}_2$ Act as oxidant:

$H_2{O}_2+2H^{+}+2e^{-}\to 2H_{2}O$ (In acidic medium)

$H_{2}O+2e^{-}\to 2O{H}^{-}$ (In basic medium)

$H_2{O}_2$ Acts as reductant:-

$H_2{O}_2\to 2H^{+}+O_2+2e^{-}$ (In acidic medium)

$H_2{O}_2+2O{H}^{-}\to 2H_{2}O+O_2+2e^{-}$ (in basic medium)
