Chapter 20, Problem 45QRT

(a)

Interpretation Introduction

Interpretation:

Ligands and the charge of the ligands has to be identified in the complex ion ${{\text{[Co(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{2}}{\text{Cl}}_{\text{2}}\text{]}}^{\text{3-}}$.

(b)

Interpretation Introduction

Interpretation:

Charge on the central metal ion in the complex ion ${{\text{[Co(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{2}}{\text{Cl}}_{\text{2}}\text{]}}^{\text{3-}}$ has to be determined.

(c)

Interpretation Introduction

Interpretation:

Formula and charge of the complex ion has to be given if the oxalate ligands are replaced by ammonia molecules.
