A solution contains some or all of the ions Cu2 Cu2 , Al3 Al3 , K K , Ca2 Ca2 , Ba2 Ba2 , Pb2 Pb2 , and NH4 NH4 . The following tests were performed, in order, on the solution. Addition of 6 MM HClHCl produced no reaction. Addition of H2SH2S with 0.2 MM HClHCl produced a black solid. Addition of (NH4)2S(NH4)2S produced a white solid. Addition of (NH4)2HPO4(NH4)2HPO4 in NH3NH3 produced no reaction. The final supernatant when heated produced a purple flame. Identify which of these ions were present in the solution, which were absent, and for which ones no conclusions can be drawn. Drag the appropriate items to their respective bins.
