Answer 2

Explanation:

Lead sulphate is insoluble in water whereas lead chloride is soluble. By dissolving the mixture of lead sulphate and lead chloride in water we can separate the two. After dissolving the mixture in water, lead sulphate can be obtained as the solid that's left behind. Lead chloride can be recovered by evaporating the solution.
