# Choosing Only Substances from the List Given in the Box Below, Write Equations for the Reactions Which You Would Use in the Laboratory to Obtain: - Chemistry

Sum

Choosing only substances from the list given in the box below, write equations for the reactions which you would use in the laboratory to obtain:
(i) Sodium sulphate
(ii) Copper sulphate
(iii) Iron (II) sulphate
(iv) Zinc carbonate

 Dilute sulphuric acid Copper, Iron,Sodium, Zinc Copper carbonate,Sodium carbonate

#### 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 :
$\ce{Zn + H2SO4(dil) → ZnSO4 + H2}$

$\ce{ZnSO4 + Na2CO3 → ZnCO3 + Na2SO4}$

Is there an error in this question or solution?
