Solution

Given below are the balanced chemical equations for the preparation of:

(i) Iron (II) sulphate from iron:

Fe + H₂SO₄ → FeSO₄ + H₂

(ii)Copper sulphate from copper:

Cu + 2H₂SO₄ → CuSO₄ + 2H₂O + SO₂

(iii) Lead sulphate from lead nitrate:

Pb(NO₃)₂+ H₂SO₄ → PbSO₄↓ + 2HNO₃

(iv) Sodium sulphate from sodium carbonate:

Na₂CO₃ + H₂SO₄ →Na₂SO₄ + H₂O + CO₂
