Answer
Preparation of lead sulphate from lead chloride:
- Dissolve lead chloride (PbCl2) in hot water as the salt is only sparingly soluble in cold water but dissolves better when heated.
- While the solution is still hot, slowly add a dilute solution of sulphuric acid with constant stirring.
- Allow the mixture to cool, then filter to collect the precipitate.
- Wash the precipitate with distilled water and finally dry it.
