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