A solution contains one or more of the following ions: Ag+, Ca2+, and Co2+. 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.
Write a net ionic equation for the formation of the precipitate observed after the addition of lithium phosphate. Include physical state

Lithium bromide is added to the solution and no precipitate forms. It can be deduced that the solution does not contain Ag⁺ ion.
When an excess of lithium sulfate is then added, the precipitate formed is calcium sulfate. The net ionic equation is:
Ca²⁺(aq) + SO₄²⁻(aq) → CaSO₄(s)
When lithium phosphate is added to the remaining solution, the precipitate formed is cobalt phosphate. The net ionic equation is:
3Co²⁺(aq) + 2PO₄³⁻(aq) → Co₃(PO₄)₂(s)
When an excess of lithium sulfate is then added, the precipitate formed is calcium sulfate. The net ionic equation is:
Ca²⁺(aq) + SO₄²⁻(aq) → CaSO₄(s)
When lithium phosphate is added to the remaining solution, the precipitate formed is cobalt phosphate. The net ionic equation is:
3Co²⁺(aq) + 2PO₄³⁻(aq) → Co₃(PO₄)₂(s)
