Concept explainers
(a)
Interpretation:
The formula of the coordination compound formed by Cu+ with NH3 needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The
(b)
Interpretation:
The formula of the coordination compound formed by Pt2+ with oxalate ion needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands. The total charge present on any complex ion is equal to the sum of the oxidation number of the central metal atom and the total charges of the ligand present in it.
(c)
Interpretation:
The formula of the coordination compound formed by Cd2+ with H2 O needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands. The total charge present on any complex ion is equal to the sum of the oxidation number of the central metal atom and the total charges of the ligand present in it.
(d)
Interpretation:
The formula of the coordination compound formed by Fe3+ with cyanide ions needs to be determined.
Concept introduction:
Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cationic or anionic. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

- Use the formation constant of [Au(CN)2] in Appendix K to determine the equilibrium concentration of Au+(aq) in a solution that is 0.0071 M CN and 1.1 104 M [Au(CN)2]. Is it reasonable to conclude that 100% of the gold in solution is present as the [Au(CN)2] complex ion?
