Chapter 19, Problem 70AE

(a)

Interpretation Introduction

Interpretation: The complex ion, the counter ions, the electronic configuration of the transition metal and the geometry of the complex needs to be determined for the complex ion ${\text{CoCl}}_{\text{2}}{\text{.6H}}_{\text{2}}\text{O}$ or $\left[\text{Co}{\left({\text{H}}_{\text{2}}\text{O}\right)}_{\text{6}}\right]{\text{Cl}}_{\text{2}}$ .

Concept Introduction: In the coordination complexes, the neutral molecule or ions form coordinate bonds with central metal atom. Generally, metals belonging to d-block undergo formation of coordinate complexes. In these complexes, the metal atom and ligand are bonded together via coordinate bonds.

(b)

Interpretation Introduction

Interpretation: The complex ion, the counter ions, the electronic configuration of the transition metal and the geometry of the complex needs to be determined for the complex ion ${\text{Na}}_3\left[\text{Ag}{\left({\text{S}}_{\text{2}}{\text{O}}_{\text{3}}\right)}_{\text{2}}\right]$ .

Concept Introduction: In the coordination complexes, the neutral molecule or ions form coordinate bonds with central metal atom. Generally, metals belonging to d-block undergo formation of coordinate complexes. In these complexes, the metal atom and ligand are bonded together via coordinate bonds.

(c)

Interpretation Introduction

Interpretation: The complex ion, the counter ions, the electronic configuration of the transition metal and the geometry of the complex needs to be determined for the complex ions formed from $\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{\text{Cl}}_{\text{2}}$ and $\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\text{Cl}$ .
