Solution

Preparation of lead chloride from lead carbonate involves two steps. That is, at first, lead carbonate is treated with nitric acid. The chemical equation for the reaction is,
$P b C O_{3} + 2 N H O_{3} \to P b (N O_{3})_{2} + H_{2} O + C O_{2}$

In the second step, lead nitrate formed is treated with hydrochloric acid to give lead chloride. The chemical equation for the reaction is,

$P b (N O_{3})_{2} + 2 H C l \to P b C l_{2} + 2 H N O_{3}$
