Question

Choosing only substances from the list given in the box below, write equations which you would use in the laboratory to obtain:

(a) Sodium sulphate,

(b) Copper sulphate

(c) Iron (II) sulphate

(d) Zinc carbonate

Dilute                         Sulphuric acid	Copper	Copper   Carbonate
	Iron	Sodium Carbonate
	Sodium
	Zinc

Answer 1

(a) Sodium sulphate:

Na₂CO₃ + H₂SO₄ (dil) ⟶ Na₂SO₄ + H₂O + CO₂

(b) Copper sulphate:

CuCO₃ + H₂SO₄ (dil) ⟶ CuSO₄ + H₂O + CO₂

(c) Iron (II) sulphate:

Fe + H₂SO₄ (dil) ⟶ FeSO₄ + H₂

(d) Zinc Carbonate:

Zn + H₂SO₄(dil) ⟶ ZnSO₄ + H₂

ZnSO₄ + Na2CO₃ ⟶ ZnCO₃ + Na₂SO₄
