Solution

(i) Iron (II) sulphate is prepared in the displacement reaction that takes place between iron and dilute sulphuric acid.

$Fe + dil . H_{2} {SO}_{4} \overset{}{\to} {FeSO}_{4} + H_{2} Iron Sulphuric acid Iron (II) sulphate Hydrogen$

(ii) Copper sulphate is prepared in the reaction that takes between copper oxide and dilute sulphuric acid.

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

(iii) Lead sulphate is prepared by treating lead nitrate with dilute sulphuric acid.

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

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

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