Current Question (ID: 8697)

Question:

$\text{The oxidising nature of H}_2\text{O}_2 \text{ is shown in the reaction-}$

Options:

1. $\text{H}_2\text{O}_2 + 2\text{KI} \rightarrow 2\text{KOH} + \text{I}_2$
2. $\text{Cl}_2 + \text{H}_2\text{O}_2 \rightarrow 2\text{HCl} + \text{O}_2$
3. $\text{H}_2\text{O}_2 + \text{Ag}_2\text{O} \rightarrow 2\text{Ag} + \text{H}_2\text{O} + \text{O}_2$
4. $\text{NaClO} + \text{H}_2\text{O}_2 \rightarrow \text{NaCl} + \text{H}_2\text{O} + \text{O}_2$

Solution:

$\text{Hint: In an oxidation reaction, H}_2\text{O}_2 \text{ itself undergo a reduction reaction.}$ $\text{H}_2\text{O}_{2(\text{aq})} + 2\text{KI}_{(\text{aq})} \rightarrow \text{I}_{2(\text{s})} + 2\text{KOH}_{(\text{aq})}$ $\text{This is an oxidation-reduction (redox) reaction:}$ $2\text{I}^{-1} - 2\text{e}^- \rightarrow 2\text{I}^0 \text{ (oxidation)}$ $2\text{O}^{-1} + 2\text{e}^- \rightarrow 2\text{O}^{-2} \text{ (reduction)}$ $\text{KI is a reducing agent, H}_2\text{O}_2 \text{ is an oxidizing agent.}$ $\text{In options 2, 3, and 4th H}_2\text{O}_2 \text{ acts as a reducing agent.}$
