AIIMS 2018 Chemistry Reactions of Permanganate MCQ Question

When KMnO₄ is added to KOH, it undergoes a redox reaction where the purple permanganate ion (MnO₄⁻) is reduced to manganese(II) ions (Mn²⁺) in an alkaline medium, resulting in a green solution due to the formation of manganate ions (MnO₄²⁻). Option A (pale pink) is incorrect as KMnO₄ appears purple, not pale pink, in neutral or acidic conditions. Option B (brown) does not apply since no brown intermediate is formed in this reaction, and option C (black) is incorrect as no black precipitate is produced under these conditions.
