Question

The reaction, $H_{2}S+H_2{O}_2\to S+2H_{2}O$ manifests:

• A. Oxidising action of $H_2{O}_2$
• B. Reducing nature of $H_2{O}_2$
• C. Acidic nature of $H_2{O}_2$
• D. Alkaline nature of $H_2{O}_2$

Answer 1

Answer: (A)

Oxidising action of $H_2{O}_2$

In $H_2{O}_2$ oxygen is present in -1 oxidation state and in $H_2{O}^{}$ it is present in -2 oxidation state so it gets reduced.

So $H_2{O}_2$ acts as an oxidising agent. It has oxidised $H_{2}S$ to $S$.
