Hg2^+2 + 2Cl^- ==> Hg2Cl2(s)
Fe^+2 + CO3^-2 ==> FeCO3(s)
You should add (aq) after the ions
A solution contains the following ions: Hg2(2+) and Fe(2+). 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. Write net ionic equations for the formation of each of the precipitates observed.
