Solution

(a) Zinc sulphate is prepared by displacement reaction between zinc and dilute sulphuric acid.

$Zn + dil . H_{2} {SO}_{4} \to {ZnSO}_{4} + H_{2}$

(b) Copper sulphate is prepared by the neutralisation reaction of copper oxide with dilute sulphuric acid.

$CuO + dil . H_{2} {SO}_{4} \to {CuSO}_{4} + H_{2} O$

(c) Sodium sulphate is prepared by the neutralisation of soluble base i.e. sodium carbonate with dilute sulphuric acid.

${Na}_{2} {CO}_{3} + dil . H_{2} {SO}_{4} \to {Na}_{2} {SO}_{4} + H_{2} O + {CO}_{2}$

(d) Lead sulphate: Preparation of lead sulphate from lead carbonate involves the following steps:

Step 1: Insoluble lead carbonate first reacts with dilute nitric acid to form soluble lead nitrate.

${PbCO}_{3} + 2 {HNO}_{3} \to Pb ({NO}_{3})_{2} + H_{2} O + {CO}_{2}$

Step 2: Dilute sulphuric acid is added to lead nitrate to form lead sulphate and nitric acid.

$Pb ({NO}_{3})_{2} + dil . H_{2} {SO}_{4} \to {PbSO}_{4} + 2 {HNO}_{3}$
