Concept explainers
(a)
Interpretation:
The oxidation state of the metal in the given compound should be determined.
Concept Introduction:
Coordination compounds: A coordination compound contains at least one complex ion, which consists of a central metal cation bonded to molecules and (or) anions called ligands.
Oxidation states: Some rules are followed by it is oxidation state in Roman numerical in parenthesis. Knowing the charge on a complex ion and the charge ligand one can determined the oxidation number for the metal.
For example:
(b)
Interpretation:
The oxidation state of metal should be identified for the given coordination compound.
Concept introduction:
Coordination compounds: A coordination compound contains at least one complex ion, which consists of a central metal cation bonded to molecules and (or) anions called ligands.
Oxidation number of central atom: The oxidation number of central atom in a complex is defined as the charge it would carry if all the ligand is removed along with the electron pairs that are shared with the central atom.
(c)
Interpretation:
The oxidation state of metal should be identified for the given coordination compound.
