Chapter 21, Problem 39E

(a)

Interpretation Introduction

Interpretation: The formulas of the given complex compounds are to be stated.

Concept introduction: Rules followed in the naming of coordination compound:

• Greek prefix is used to express the number of ligands.

• Roman numeral is used to denote the oxidation state of metal ion.

• In case of more than one type of ligand present in a compound, they are named alphabetically.

• The suffix ‘-ate’ is added to metal ion if complex ion contains negative charge. Latin names are also used to identify the name of metals.

• If counter ions are present in complex compound, then cation is named first which is the name of element, whereas anion is named last which is the name of salt.

To determine: The formula of the complex compound potassium tetrachlorocobaltate(II).
