What two aqueous reactant might you combine to give a leadII

What two aqueous reactant might you combine to give a lead(II) carbonate precipitate? Write the molecular equation for the reaction that would result.

Solution

From given statement it is clear that lead carbonate is insoluble in water.This means we have to choose such a salt of lead and carbonate that are soluble in water.Since sulfates and chlorides of lead are almost insoluble in water ,so, these salts can\'t be chosen.So the other salt of lead that can be used is lead acetate and salt of carbonate that is soluble in water and can be used is ammonium carbonate.The reaction for this can be written as follows:

Pb(CH3COO)2 + (NH4)2CO3----------> PbCO3+2NH4(CH3COO)
