Chapter 15, Problem 15.94QE

(a)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M{\text{ NH}}_3$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Spectator ions are regarded as ions that confer no acidic or basic properties to the overall ionic equation of an acid-base reaction. This is because they are usually the conjugate base corresponding to strong acids such as chloride, iodide, bromide, or nitrate ions or cation of alkali metal hydroxides such as ${\text{Na}}^{+}$ and ${\text{K}}^{+}$.

(b)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M{\text{ Na}}_2{\text{CO}}_{\text{3}}$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M\text{ NaCl}$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M{\text{ CH}}_3\text{COOH}$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Refer to part (a).

(e)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M{\text{ NH}}_4\text{Cl}$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Refer to part (a).

(f)

Interpretation Introduction

Interpretation:

Whether the solution of $0.1M{\text{ NaCH}}_3{\text{CO}}_{\text{2}}$ is acidic, neutral, or basic has to be stated.
