Chapter 23, Problem 23.51P

(a)

Interpretation Introduction

Interpretation:

For the given complex the charge and coordination number of the central metal ion(s) has to be find out.

  $K\left[Ag{\left(CN\right)}_2\right]$

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.

(b)

Interpretation Introduction

Interpretation:

For the given complex the charge and coordination number of the central metal ion(s) has to be find out.

  $N{a}_2\left[CdC{l}_4\right].$

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.

(c)

Interpretation Introduction

Interpretation:

For the given complex the charge and coordination number of the central metal ion(s) has to be find out.

  $\left[\text{Co }{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\left({\text{H}}_{\text{2}}\text{O}\right)\text{ Br}\right]{\text{Br}}_{\text{2}}\text{. }$
