Chapter 17, Problem 4E

Interpretation Introduction

(a)

Interpretation:

The oxidation number for ${\text{Au}}^{+3}$ is to be stated.

Concept introduction:

The oxidation number is the positive or negative value assigned to an atom in a substance. The number of electrons lost or gained by the elements gives the value of oxidation number. The oxidation number of monoatomic ion is equal to its charge.

Interpretation Introduction

(b)

Interpretation:

Concept introduction:

The oxidation number is the positive or negative value assigned to an atom in a substance. The number of electrons lost or gained by the elements gives the value of oxidation number. The oxidation number of monoatomic ion is equal to its charge.

Interpretation Introduction

(c)

Interpretation:

The oxidation number for ${\text{P}}^{3-}$ is to be stated.

Concept introduction:

The oxidation number is the positive or negative value assigned to an atom in a substance. The number of electrons lost or gained by the elements gives the value of oxidation number. The oxidation number of monoatomic ion is equal to its charge.

Interpretation Introduction

(d)

Interpretation:

The oxidation number for ${\text{O}}^{2-}$ is to be stated.

Concept introduction:

The oxidation number is the positive or negative value assigned to an atom in a substance. The number of electrons lost or gained by the elements gives the value of oxidation number. The oxidation number of monoatomic ion is equal to its charge.
