Chapter 19, Problem 51E

Interpretation Introduction

Interpretation: The reason for the compounds of ${\text{Ti}}^{\text{3+}}$ and ${\text{V}}^{\text{3+}}$ being colored and ${\text{Sc}}^{\text{3+}}$ are not colored needs to be explained.

Concept introduction: Transition metals generally have partially filled $\text{d or f}$ orbitals. The splitting of d-orbitals due to interaction of ligands with metal and transfer of electrons between these split d-orbitals results in colored metal.
