BaCO3↓ + 2AcOH -> Ba(AcO)2 + CO2↑ + H2O — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Barium carbonate (BaCO3↓) is an insoluble carbonate precipitate. Step 2: Acetic acid (AcOH), although a weak acid, is sufficiently acidic to decompose the carbonate, forming soluble barium acetate, Ba(AcO)2, along with water and escaping carbon dioxide gas. Step 3: Because the solid precipitate is dissolved into a clear solution, this is classified as a precipitate dissolution reaction (type B), matching option (b).
