A solution contains one or more of the following ions: Hg2 2+,Ba2+ ,Fe2+ and . When potassium chloride is added to the solution, a precipitate forms. The precipitate is filtered off and potassium sulfate is added to the remaining solution, producing no precipitate. When potassium carbonate is added to the remaining solution, a precipitate forms.Fe2+ and Hg2 2+ were present in the original solution.
Write net ionic equations for the formation of each of the precipitates observed.

Hg2^+2(aq) + 2Cl^-(aq) ==> Hg2Cl2(s)

iron carbonate is done the same way.
