Current Question (ID: 8686)

Question:

$\text{H}_2\text{O}_2 \text{ acts as a -}$

Options:

1. $\text{Bleaching agent}$
2. $\text{Oxidising agent}$
3. $\text{Oxidant for a rocket fuel}$
4. $\text{All of the above}$

Solution:

$\text{Hint: H}_2\text{O}_2 \text{ is an oxidizing agent}$ $\text{Explanation:}$ $\text{H}_2\text{O}_2 \text{ can act both as a reducing agent and oxidizing agent. The oxidation reaction is as follows:}$ $\text{PbS} + 4\text{H}_2\text{O}_2 \rightarrow \text{PbSO}_4 + 4\text{H}_2\text{O} \text{ (oxidation reaction)}$ $\text{Due to its oxidizing nature, H}_2\text{O}_2 \text{ acts as the bleaching agent.}$ $\text{H}_2\text{O}_2 \rightarrow \text{H}_2\text{O} + [\text{O}]$ $\text{Coloured material} + [\text{O}] \rightarrow \text{Colourless material}$
