Vedclass · Answer

(D) An oxidizing agent is a substance that gains electrons and gets reduced in a chemical reaction. For a substance to act as an oxidizing agent,the central atom must be in an oxidation state from which it can be reduced to a lower oxidation state. In $O_2$,oxygen is in $0$ oxidation state and can be reduced to $-2$. In $KMnO_4$,manganese is in $+7$ oxidation state,which is its maximum,so it can be reduced. In $H_2O_2$,oxygen is in $-1$ oxidation state and can be reduced to $-2$. In $I^-$,iodine is in $-1$ oxidation state,which is its minimum possible oxidation state for iodine. Therefore,it can only be oxidized to $I_2$ or other higher oxidation states,but it cannot be reduced further. Thus,$I^-$ acts only as a reducing agent.
