Chapter 17.1, Problem 17.1E

(a)

Interpretation Introduction

Interpretation:

The oxidation number of nitrogen in ${\text{N}}_{\text{2}}$ has to be determined.

Concept Introduction:

The oxidation state is also known as oxidation number.  For example the oxidation state of nitrogen in ammonia $\left({\text{NH}}_{\text{3}}\right)$ is $-3$.  It depicts the ability of a particular atom to accept or give up electrons.  Oxidation number may have values which can be negative ,positive or even zero.

(b)

Interpretation Introduction

Interpretation:

The oxidation number of nitrogen in ${\text{NO}}_3^{-}$ has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The oxidation number of nitrogen in ${\text{NH}}_4^{+}$ has to be determined..

Concept Introduction:
