Na2SO3 + BaCl2 -> BaSO3↓ + 2NaCl — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Sodium sulfite (Na2SO3) and barium chloride (BaCl2) are highly soluble in water. Step 2: Mixing these solutions results in the formation of insoluble barium sulfite, BaSO3↓, which precipitates. Step 3: Thus, this is a precipitate formation reaction (type A), corresponding to option (a).
