A solution contains some or all of the ions Cu²*, AP+, K*, Ca²+, Ba", Pb, and NH,* The following tests were performed, in order, on the solution. 1. Addition of 6 M HCl produced no reaction 2. Addition of H,S with 02 M HCl produced a black solid. 3. Addition of (NH,),S produced a white solid 4. Addition of (NH,),HPO, in NH, produced no reaction. 5. The final supenatant 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
