Chapter 23, Problem 23.54P

(a)

Interpretation Introduction

Interpretation:

The correct formula for the given names has to be given.

Dibromobis (ethylene diamine) cobalt (III) sulfate

Concept introduction:

Coordination number:

The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.

Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.

1. 1. The cation is named before the anion.
2. 2. Within a complex ion, the Ligands are arranged in an alphabetical order followed by the metal ion name. The anionic Ligand should ends with a letter –o, the neutral Ligand are called by the molecules (some common name for some exception).
3. 3. When more Ligands are present, Greek prefixes like di, tri, tetra, penta, and hexa to specify their number.
4. 4. The oxidation number of the metal is represented in roman numerals immediately following the metal ion name.
5. 5. If the complex ion is an anion, the metal name should end with –ate.
