Chapter 22, Problem 12QP

Interpretation Introduction

Interpretation:

The oxidation number of the metal in the given compoundis to be determined.

Concept introduction:

Coordination compounds are the compounds formed by the reaction of metal ions with polar molecules, or with a group of anions. They contain coordinate covalent bonds.

Oxidation number is also called the oxidation state. It is used to describe the oxidation, that is, theloss of electrons, in any compound.

The overall charge can be calculated by adding the total charge on the complex.

Alkali metal cation (potassium) has charge +1

Cyanide ligands have a negative charge of $\left(-1\right)$.

Oxalate ligand has a $-2$ charge.
