solution contains one or more of the following ions: \( \mathrm{Ag}^{+}, \mathrm{Ca}^{2+} \), and \( \mathrm{Co}^{2+} \), Lithium bromide is added to the solution and no precipitate forms. An excess of lithium sulfate is then added to the solution and a precipitate forms. The precipitate is filtered off and lithium phosphate is added to the remaining solution, producing a precipitate.
Which ions are present in the original solution?
\( \mathrm{Ca}^{2+} \)
\( \mathrm{Ag}^{+} \)
\( \mathrm{Co}^{2+} \)
Write a net ionic equation for the formation of the precipitate observed after the addition of lithium sulfate. Include physical states.
net ionic equation: \( \square \)
