AgCl on fusion with sodium carbonate, gives : — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: When silver chloride (AgCl) is fused with anhydrous sodium carbonate (Na2CO3), a displacement reaction occurs. Step 2: This reaction is represented as: 4AgCl + 2Na2CO3 -> 4NaCl + 2CO2 + O2 + 4Ag. Step 3: The silver carbonate/oxide formed intermediately is thermally highly unstable at fusion temperatures and decomposes completely into metallic silver (Ag). Thus, option (c) is correct.
