Solution
(i) Preparation of Sodium Sulphate :
Sodium Carbonate + Dilute Sulphuric acid → Sodium Sulphate + Water + Carbon dioxide.
\[\ce{Na2CO3 + H2SO4 →Na2SO4 + H2O + CO2}\]
(ii) Preparation of Copper Sulphate :
Copper Carbonate + dilute Sulphuric acid → Copper Sulphate + water + carbon dioxide.
\[\ce{CuCO3 + H2SO4 → CuSO4 + H2O + CO2}\]
(iii) Preparation of iron (II) sulphate :
Iron + dilute Sulphuric acid → Iron (II) Sulphate + Hydrogen
\[\ce{Fe + H2SO4 → FeSO4 + H2}\]
(iv) Preparation of Zinc Carbonate :
\[\ce{Zn + H2SO4(dil) → ZnSO4 + H2}\]
\[\ce{ZnSO4 + Na2CO3 → ZnCO3 + Na2SO4}\]
