The preparation of lead sulphate from lead carbonate is a two-step process.
(lead sulphate cannot be prepared by adding dilute sulphuric acid to lead carbonate)
(b) Write the equation for the reaction that will take place when the first step is carried out

Solution

The first step is to convert insoluble lead carbonate into soluble lead nitrate by treating lead carbonate with dilute nitric acid. The equation can be given as,

$P b C O_{3} (s) + 2 H N O_{3} (dil.) \to P b (N O_{3})_{2} (aq) + H_{2} O (l) + C O_{2} ↑$
