Vedclass · Answer

(D) substance can act as both an oxidizing and a reducing agent when the central atom is in an intermediate oxidation state.In $SO_2$,the oxidation state of sulfur is $+4$. Since sulfur can range from $-2$ to $+6$,it can be oxidized to $+6$ or reduced to lower states,thus acting as both.In $H_2O_2$,the oxidation state of oxygen is $-1$. Since oxygen can range from $-2$ to $0$,it can be reduced to $-2$ or oxidized to $0$,thus acting as both.Therefore,both $H_2O_2$ and $SO_2$ can act as both oxidizing and reducing agents.
