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

उत्तर
Lead carbonte and lead sulphate both are insoluble in water. So when dilute H2SO4 is added to lead carbonate, lead sulphate formed deposits on the remaining lead carbonate thereby stopping the further reaction.
