Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics.
Qualitative Analysis of Metal Cations Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics. One such scheme is shown in the flow diagram. Some ions that are soluble in all of the test solutions can still be identified based on flame tests. Certain ions impart characteristic color to the flame.Part AA solution contains some or all of the ions Cu2+, Al3+, K+, Ca2+, Ba2+, Pb2+, and NH4+. The following tests were performed, in...
