Question
### Qualitative Analysis of Group II Cations Qualitative analysis is a method for identifying the elements present in an unknown mixture. For this purpose, metal cations are broadly classified into three groups based upon their solubilities: - **Group I cations**, \( \text{Pb}^{2+} \), \( \text{Ag}^{+} \), and \( \text{Hg}_2^{2+} \), form insoluble chlorides. - **Group II cations**, \( \text{Cu}^{2+} \), \( \text{Bi}^{3+} \), \( \text{Hg}^{2+} \), \( \text{Cd}^{2+} \), \( \text{Sn}^{4+} \), \( \text{Sb}^{3+} \), form insoluble sulfides below pH 0.5. - **Group III cations**, \( \text{Al}^{+} \), \( \text{Cr}^{+} \), \( \text{Co}^{+} \), \( \text{Fe}^{+} \), \( \text{Mn}^{+} \), \( \text{Ni}^{+} \), \( \text{Zn}^{+} \), form insoluble sulfides above pH 9. - **Group IV cations**, \( \text{Ba}^{2+} \), \( \text{Ca}^{2+} \), \( \text{Mg}^{2+} \), \( \text{Na}^{+} \), \( \text{K}^{+} \), \( \text{NH}_4^{+} \), are the remaining common cations. The alkaline earth members of this group form insoluble carbonates while the alkaline elements are identified by flame tests. The ammonium ion is detected by a litmus test. These groups are easily separated by their markedly different solubilities. Separating the cations within a given group is more difficult, but based upon the same principle, as will be shown in the experimental section. **Note:** The groups used for quantitative analysis are solely based on solubility. They do not in any way correspond to the groups of the periodic table. --- ### Group II Cations: \( \text{Cu}^{2+} \), \( \text{Bi}^{3+} \), \( \text{Sn}^{4+} \), \( \text{Sb
