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)
(c) Why is the direct addition of dilute sulphuric acid to lead carbonate an impractical method of preparing lead sulphate?

Open in App

Solution

Lead carbonate and lead sulphate are insoluble in water. Therefore, when dilute $H_{2} S O_{4}$ is added to lead carbonate, lead sulphate formed deposits on the remaining lead carbonate thereby stopping the further reaction.
