Current Question (ID: 8705)

Question:

$\text{Reaction among the following where H}_2\text{O}_2 \text{ acts as a reducing agent is-}$

Options:

1. $\text{a, b}$
2. $\text{c, d}$
3. $\text{a, c}$
4. $\text{b, d}$

Solution:

$\text{Hint: Reduction reaction oxidation state decreases.}$ $\text{If H}_2\text{O}_2\text{ acts as a reducing agent then itself it undergoes an oxidation reaction. In the option, b and d electrons are minus from H}_2\text{O}_2\text{ side. Thus, it indicates that H}_2\text{O}_2\text{ undergo oxidation and acts as a reducing agent.}$ $\text{b. H}_2\text{O}_2 - 2\text{e}^- \rightarrow \text{O}_2 + 2\text{H}^+$ $\text{H}_2\text{O}_2 \rightarrow \text{O}_2 + 2\text{H}^+ + 2\text{e}^-$ $\text{d. H}_2\text{O}_2 + 2\text{OH}^- - 2\text{e}^- \rightarrow \text{O}_2 + 2\text{H}_2\text{O}$ $\text{H}_2\text{O}_2 + 2\text{OH}^- \rightarrow \text{O}_2 + 2\text{H}_2\text{O} + 2\text{e}^-$ $\text{The reaction given in a and c is a reduction reaction.}$
