Chapter 22, Problem 62AP

Interpretation Introduction

Interpretation:

The statement thathydrated ${\text{Mn}}^{2+}$ is colorless even though it possesses five $3d$ electrons is to beexplained.

Concept introduction:

The hydrated complex of ${\text{Mn}}^{2+}$ is ${\text{[Mn}{\left({\text{H}}_2\text{O}\right)}_6]}^{2+}$, which is a coordination compound containing six aqua ligands and manganese as a central metal. The complex is ${\text{sp}}^3{\text{d}}^2$ hybridized and has octahedral geometry. ${\text{[Mn}{\left({\text{H}}_2\text{O}\right)}_6]}^{2+}$ is a weakly colored complex.
