Vedclass · Answer

(D) The chemical reaction is: $SO_{2} + 2H_{2}S \rightarrow 3S + 2H_{2}O$.In this reaction,$SO_{2}$ oxidizes $H_{2}S$ to $S$ and itself gets reduced to $S$.Since $SO_{2}$ causes the oxidation of $H_{2}S$,it acts as an oxidizing agent.Option $D$ states that it acts as a weak bleaching agent. While $SO_{2}$ is a bleaching agent,this property is not relevant to the chemical reaction described in the question. Therefore,the statement in option $D$ is incorrect in the context of this specific reaction.
