Chapter 7, Problem 107P(choose chapter or problem)
A solution contains one or more of the following ions: \(A g^{+}\), \(C a^{2+}\), and \(C u^{2+}\). When sodium chloride is added to the solution, no precipitate occurs. When sodium sulfate is added to the solution, a white precipitate occurs. The precipitate is filtered off and sodium carbonate is added to the remaining solution, producing a precipitate. Which ions were present in the original solution? Write net ionic equations for the formation of each of the precipitates observed.
