Give balanced chemical equations to prepareation of the following salts:1. Lead sulphate-from lead carbonate.2. Sodium sulphate-using dilute sulphuric acid.3. Copper chloride-using copper carbonate |
|
Answer» (1) Lead sulphate from lead carbonate. PbCO3 + HNO3 → Pb(NO3)2 + H2O + CO2 Pb(NO3)2 + H2SO4 → PbSO4 + 2HNO3 (2) Sodium sulphate using dilute sulphuric acid. Na2CO3 + H2SO4 (dil) → Na2SO4 + H2O+ CO2 (3) Copper chloride using copper carbonate. CuCO3 + HCl(dil) → CuCl2 + H2O + CO2 (Insoluble) |
