Question 6 of 15 > A solution contains one or more of the following ions: Agt, 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. Which ions are present in the original solution? Agt Ca? Co2 Write a net ionic equation for the...
