Find the incorrectly matched pair? — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Match each metal with its corresponding ore: Tin is extracted from Cassiterite (SnO2, so A matches 2); Zinc is extracted from Calamine (ZnCO3, so B matches 1). Step 2: Titanium is extracted from Rutile (TiO2, so C matches 4); Lead is extracted from Cerrusite (PbCO3, so D matches 3). Step 3: This matching gives (A)-2, (B)-1, (C)-4, (D)-3, which corresponds to option (b).
