Hydrogen Peroxide

Question

H₂O₂ → 2H⁺ + O₂ + 2e^– ; E₀ = – 0.68V. The above equation represents which of the following behaviour of H₂O₂?

Easy

A

Oxidising
B

Reducing
C

Acidic
D

Catalytic

Solution

: E° = -0.68V.
→ In the above equation H₂O₂ itself undergoes oxidation. Therefore in the above equation H₂O₂ acts (or) behaves as reducing agent (reductant)
Note :- The substances which reduces the another substance and itself undergoes oxidation is said to be reducing agent.
i.e., An agent which brings the reduction in another substance is called reductant.
