Carbonates

Explain, why ...

Question

Explain, why the following statement is not correct:
Lead chloride can be prepared by adding dilute HCl to lead sulphate solution.

Open in App

Solution

Lead sulphate will not react with dilute hydrochloric acid. A white precipitate of lead chloride is obtained when hydrochloric acid is added to a lead nitrate solution.

Pb(NO₃)₂(aq) + 2HCl(aq) → PbCl₂(s) + 2HNO₃(aq)
