Chapter 17, Problem 21AE

(a)

Interpretation Introduction

Interpretation:

Whether pair $\text{Zn}$ and ${\text{CuSO}}_4$ react in water solution or not has to be determined.

Concept Introduction:

Among the metals in electrochemical series that are $\text{K}$, $\text{Ca}$, $\text{Mg}$, $\text{Al}$, $\text{Zn}$, $\text{Fe}$, $\text{H}$, $\text{Cu}$ and $\text{Ag}$.the ones above hydrogen are less reactive than hydrogen. The ones that are below hydrogen are more reactive than hydrogen. The arrangement is done in reactivity order that is $\text{K}$ is most reactive and $\text{Ag}$ is least reactive. Least reactive metal cannot displace more reactive metal due to this reaction does not occur.

(b)

Interpretation Introduction

Interpretation:

Whether pair $\text{Cu}$ and ${\text{Al}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}$ react in water solution or not has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Whether pair $\text{Fe}$ and ${\text{AgNO}}_3$ react in water solution or not has to be determined.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Whether pair $\text{Zn}$ and $\text{Ca}{\left({\text{NO}}_3\right)}_2$ react in water solution or not has to be determined.

Concept Introduction:

Refer to part (a).

(e)

Interpretation Introduction

Interpretation:

Whether pair $\text{Ag}$ and $\text{HCl}$ react in water solution or not has to be determined.

Concept Introduction:

Refer to part (a).

(f)

Interpretation Introduction

Interpretation:

Whether pair $\text{Mg}$ and ${\text{Al}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}$ react in water solution or not has to be determined.

Concept Introduction:
