Chemistry - Redox Reactions Question with Solution | TestHub

I is correct: in ${\mathrm{S}}^{2-}$, sulphur is at its minimum oxidation state (-2), so it cannot accept electrons and can only be oxidized. II is also correct as a general statement: an oxidizing agent gains electrons and is itself reduced. But the general definition does not explain why ${\mathrm{S}}^{2-}$ specifically can never oxidize anything - the reason is sulphur's minimum oxidation state. Hence (b).
