BaSO4↓ + Na2CO3 -> BaCO3↓ + Na2SO4 — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify starting materials: Barium sulfate (BaSO4↓) is a highly insoluble white precipitate. Step 2: Analyze the reaction on boiling with Na2CO3 solution: The carbonate ions displace the sulfate ions from the solid surface to form a different insoluble solid, barium carbonate (BaCO3↓). Step 3: Since one solid precipitate is converted directly into another solid precipitate, this is classified as a precipitate exchange reaction (type C).
