Chapter 22, Problem 29QP

Interpretation Introduction

Interpretation:

The statement,“compounds containing ${\text{Sc}}^{\text{+3}}$ are not coloredwhereas compounds containing ${\text{Ti}}^{\text{+3}}$ arecolored”, is to be explained.

Concept introduction:

The transition metals are those metals that form at least one stable ion with incomplete d subshell.

A transition metal shows variable oxidation state.

The transition metals have partially filled d subshells.

When an electron jumps from one energy level to another, light is emitted.

Presence of d electron is necessary for the transition metal ions to be colored.
