WebOxalic acid reacts with potassium manganate (VII) in acidic solutions and is oxidised to carbon dioxide and water: 2MnO 4– + 5C 2 H 2 O 4 + 6H 3 O + → 2Mn 2+ + 10CO 2 + 14H 2 O. The potassium manganate (VII) decolourises which provides a convenient and easy-to-measure end-point to the reaction. Aqueous solutions of Mn 2+ are actually pale ... WebAnswer (1 of 5): Potassium citrate is a salt of weak acid, citric acid and strong base, caustic potash. It hydrolyses in water to citric acid and potassium hydroxide. As citric acid is weak acid, it almost remains undissociated in water, but as KOH is strong base, it remains in dissociated condit...
