Name the process used for the large scale manufacture of sulphuric acid.

Which property of sulphuric acid accounts for it's use as a dehydrating agent.

Write balanced equation for the following reactions:

(i) Lead sulphate from lead nitrate solution and dilute sulphuric acid.

(ii) Copper sulphate from copper and conc. sulphuric acid.

Properties of H₂SO₄ are listed below. Choose the property A, B, C or D which is responsible for the reactions (i) to (v).

A : Acid
B: Dehydrating agent
C: Non-volatile acid
D: Oxidizing agent

(i) C₁₂H₂₂O₁₁+ nH₂SO₄ ⟶ 12C + 11H₂O + nH₂SO₄

(ii) S + 2H₂SO₄ ⟶ 3SO₂ + 2H₂O

(iii) NaCl + H₂SO₄ ⟶ NaHSO₄ + HCl

(iv) CuO + H₂SO₄ ⟶ CuSO₄ + H₂O

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