Chapter 19, Problem 85AE

Interpretation Introduction

Interpretation: Whether the given reaction is in consistent with the reaction which proceeds through the formation of $\left({\text{H}}_{\text{2}}\text{O}\right)\text{Cr}-\text{Cl}-\text{Co}{\left({\text{NH}}_{\text{3}}\right)}_{\text{5}}$ as an intermediate or not needs to be explained.

  ${\text{Cr(H}}_{\text{2}}{\text{O)}}_{\text{6}}^{\text{2+}}{}_{\text{(aq)}}{\text{ + Co(NH}}_{\text{3}}{\text{)}}_5^{}{\text{Cl}}_{\text{(aq) }}^{2+}𑨀\text{ Cr(III) complex + Co(II) complex}$

Concept Introduction: A coordination complex is composed of two main parts; metal atom/ ion and ligand. Ligands are the atom/ group of atom/ ion that can donate its extra pair of electrons to the electron deficient metal cation. It leads to the formation of coordinate bond between metal ion and ligand.
