Which of the following reaction is incorrect ? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Barium acetate, Ba(AcO)2, and potassium chromate, K2CrO4, are both highly soluble salts. Step 2: Upon mixing, barium ions and chromate ions combine to form a highly insoluble yellow precipitate of barium chromate, BaCrO4↓. Step 3: Because a solid precipitate is formed from soluble reactants, this is a precipitate formation reaction (type A), matching option (a).
