Coordination compounds are inorganic compounds that contain complex ions, which are composed of central metal ions surrounded by coordinated molecules or ions called ligands. Consider the coordination compound [Ag(NH3)2]Cl. The complex ion [Ag(NH3)2]+ maintains electrical neutrality. Coordination compounds can be charged or uncharged.
Question: For the following coordination compound, identify the cation and anion by stating their formulas and charges:
4) Ca[CdCl2]
Cation: Ca2+
Anion: [CdCl2]2-
6) [Ti(H2O)6]2+
Cation: [Ti(H2O)6]2+
Anion: None
[Zn(NH3)4]2+
Cation: [Zn(NH3)4]2+
Anion: None
Question 7: Identify the ligands of each of the complex ions seen in the above question by writing the formula, charge, and number of each of the ligands:
Ca[CdCl2]
Ligands: Cl-
[Ti(H2O)6]2+
Ligands: H2O
[Zn(NH3)4]2+
Ligands: NH3
