Question

Write a balanced equation for the preparation of each of the following salts:

(i) Copper sulphate from copper carbonate. 

(ii) Zinc carbonate from zinc sulphate.

Answer 1

(i) Preparation of copper sulphate from copper carbonate can be done by reacting copper carbonate with sulphuric acid. 

CuCO₃ + H₂SO₄ ---> CuSO₄ + CO₂ + H₂O 

(ii) Zinc carbonate from zinc sulphate can be prepared by reacting zinc sulphate with sodium carbonate. 

ZnSO₄ + Na₂CO₃ ----> ZnCO₃ + Na₂SO₄
