Concept explainers
Interpretation:
The formula for the compound showing the complex ion present needs to be determined and it should be named.
Concept Introduction :
A coordinate complex is formed when an electron efficient ion or molecule share electron/s with and electron deficient metal ion.

Answer to Problem 1DQ
- Hexachloroplatinateion
- Potassium hexachloroplatinate (IV)
Explanation of Solution
When
In the compound two potassium and six chloride ions are present. Therefore, to provide a neutral compound platinum must carry +4 charge. Hence, platinum has +4 oxidation state and the name of the compound is platinum (IV), and the ligand’s number is 6 chloride ions. Cl- is selected as chloro, hexa prefix displays six Cl- ions are present.
Therefore, the name of the complex ion is thus Hexachloroplatinateion and the name of the compound is potassium hexachloroplatinate (IV).
