Chapter 17, Problem 30E

Interpretation Introduction

(a)

Interpretation:

Among the pair ${\text{Pb}}^{2+}\left(aq\right)$ and ${\text{Zn}}^{2+}\left(aq\right)$, the one having the greater tendency to be reduced is to be stated.

Concept introduction:

The oxidizing agent is a compound whose oxidation state falls during the course of the reaction and the reducing agent is the compound whose oxidation number increases. The compound having a greater tendency to be oxidized is the compound having the highest reducing power.

Interpretation Introduction

(b)

Interpretation:

Among the pair ${\text{Fe}}^{3+}\left(aq\right)$ and ${\text{A1}}^{3+}\left(aq\right)$, the one having the greater tendency to be reduced is to be stated.

Concept introduction:

The oxidizing agent is a compound whose oxidation state falls during the course of the reaction and the reducing agent is the compound whose oxidation number increases. The compound having a greater tendency to be oxidized is the compound having the highest reducing power.

Interpretation Introduction

(c)

Interpretation:

Among the pair ${\text{Ag}}^{+}\left(aq\right)$ and ${\text{I}}_2\left(s\right)$, the one having the greater tendency to be reduced is to be stated.

Concept introduction:

The oxidizing agent is a compound whose oxidation state falls during the course of the reaction and the reducing agent is the compound whose oxidation number increases. The compound having a greater tendency to be oxidized is the compound having the highest reducing power.

Interpretation Introduction

(d)

Interpretation:

Among the pair ${\text{Cu}}^{2+}\left(aq\right)$ and ${\text{Br}}_{\text{2}}\left(l\right)$, the one having the greater tendency to be reduced is to be stated.

Concept introduction:

The oxidizing agent is a compound whose oxidation state falls during the course of the reaction and the reducing agent is the compound whose oxidation number increases. The compound having a greater tendency to be oxidized is the compound having the highest reducing power.
