Chapter 21, Problem 21.66SP

Interpretation Introduction

(a)

Interpretation:

The oxidation state of the metal in complex ${\text{Co(NH}}_3{)}_3{{\text{(NO}}_{\text{2}}\text{)}}_3^{}$ needs to be determined.

Concept introduction:

Oxidation state or oxidation number indicates the extent of oxidation of the atom in the compound. It is usually represented as a positive or negative charge on the atom.

In other words, it indicates the loss of electrons of the atom in a chemical compound. The number indicates the number of electrons that an atom can gain or lose.

Interpretation Introduction

(b)

Interpretation:

The oxidation state of the metal in complex $\left[{\text{Ag(NH}}_{\text{3}}{\text{)}}_{\text{2}}\right]{\text{NO}}_{\text{3}}$ needs to be determined.

Concept introduction:

The extent of oxidation of the atom in the compound is the oxidation number or oxidation state. It is indicated as a positive or negative number.

In other words, it indicates the loss of electrons of the atom in a chemical compound. This indicates the number of electrons that an atom can gain or lose.

Interpretation Introduction

(c)

Interpretation:

The oxidation state of the metal in complex ${\text{K}}_{\text{3}}\left[\text{Cr}{\left({\text{C}}_{\text{2}}{\text{O}}_{\text{4}}\right)}_{\text{2}}{\text{Cl}}_{\text{2}}\right]$ needs to be determined.

Concept introduction:

The extent of oxidation of the atom in the compound is the oxidation number or oxidation state. It is indicated as a positive or negative number.

In other words, it indicates the loss of electrons of the atom in a chemical compound. This indicates the number of electrons that an atom can gain or lose.

Interpretation Introduction

(d)

Interpretation:

The oxidation state of the metal in complex $\text{Cs}\left[{\text{CuCl}}_{\text{2}}\right]$ needs to be determined.

Concept introduction:

The extent of oxidation of the atom in the compound is the oxidation number or oxidation state. It is indicated as a positive or negative number.

In other words, it indicates the loss of electrons of the atom in a chemical compound. This indicates the number of electrons that an atom can gain or lose.
