Chemistry
Answer
The first step is to convert insoluble lead carbonate into soluble lead nitrate by treating lead carbonate with dilute nitric acid.
PbCO3 (s) + 2HNO3(dil) ⟶ Pb(NO3)2 (aq) + H2O (l) + CO2
In the second step, the resulting solution is then treated with sulphuric acid or sodium sulphate solution and a white precipitate of lead suphate is obtained.
Pb(NO3)2 + 2NaCl ⟶ 2NaNO3 + PbCl2
