Thermal decomposition of which of the salt listed below yield a basic and acidic oxides simultaneoul — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Calcium hydroxide solution is a clear soluble base. Step 2: Passing sulfur dioxide (SO2) gas through it yields insoluble calcium sulfite, CaSO3↓. Step 3: Since a solid precipitate forms from soluble starting materials, this is a precipitate formation reaction (type A), corresponding to option (a).
