उत्तर
Lead acetate
Explanation -
Lead sulphate being insoluble in water will not react. However, lead acetate can be used since it is water soluble in nature.
`underset("Lead acetate")(("CH"_3"COO")_2) + "Pb" + 2"KI" -> underset(("yellow ppt.")) ("PbI"_2) + underset ("Pot. acetate")(2"CH"_3"COOK") `
