Name from the list of substances given below, that would be used to prepare each of the salts named in parts (a) to (d).
(The substances are copper, lead, sodium, zinc, copper oxide, lead carbonate solution, $dil . HCl$ , $dil . {HNO}_{3}$ , and $dil . H_{2} {SO}_{4}$ .)
(a) Zinc sulphate.

Solution

When zinc $(Zn)$ reacts with dilute sulphuric acid, zinc sulphate $({ZnSO}_{4})$ and hydrogen is produced.
This type of reaction is called displacement reaction.
The chemical equation representing the reaction is written below:
$Zn + H_{2} {SO}_{4} \to {ZnSO}_{4} + H_{2}$
Hence, to prepare zinc sulphate, zinc and $dil . H_{2} {SO}_{4}$ is required.
