Question

Which of the following reactions depict the oxidising action of hydrogen peroxide?

• A. $PbS\left(s\right)+H_2{O}_2\left(aq\right)\to PbS{O}_4\left(s\right)+4H_{2}O$
• B. $2I^{-}+2H^{+}+H_2{O}_2\to I_2+H_{2}O$
• C. $2F{e}^{2+}+2H^{+}+H_2{O}_2\to 2F{e}^{3+}+2H_{2}O$
• D. All of the above

Answer 1

The correct option is D All of the above

In option (a), $PbS\text{is oxidised to}PbS{O}_4\text{which shows the oxidising action of}{H}_2{O}_2$
In option (b), $I^{-}\text{is oxidised to}{I}_2\text{which shows the oxidising action of}{H}_2{O}_2$
In option (c), $F{e}^{2+}\text{is oxidised to}F{e}^{3+}\text{which shows the oxidising action of}{H}_2{O}_2$
Hence, option (d) is the correct answer.
