Vedclass · Answer

(C) To act as a reducing agent,a species must be able to increase its oxidation state (i.e.,undergo oxidation).In $SO_2$,the oxidation state of $S$ is $+4$ (can increase to $+6$).In $SO_3^{2-}$,the oxidation state of $S$ is $+4$ (can increase to $+6$).In $S^{2-}$,the oxidation state of $S$ is $-2$ (can increase to $0$ or higher).In $H_2SO_4$,the oxidation state of $S$ is $+6$,which is the maximum possible oxidation state for sulphur.Therefore,$H_2SO_4$ cannot be further oxidized and cannot act as a reducing agent.
