Chapter 11, Problem 28E

(a)

Interpretation Introduction

Interpretation: The strongest oxidizing agent from the given species needs to be identified.

  ${\text{Na}}^{\text{+}}\text{,}{\text{Cl}}^{-}\text{,}{\text{Ag}}^{\text{+}}\text{,}\text{Ag,}{\text{Zn}}^{\text{2+}}\text{,}\text{Zn}\text{and}\text{Pb}$

Concept Introduction: The substance that can easily reduce is oxidizing agent. They are on left side of reduction half reactions.

The substances that get easily oxidized are reducing agent. They are on right side of the reduction half reactions.

(b)

Interpretation Introduction

Interpretation: The strongest reducing agent from the given species needs to be identified.

  ${\text{Na}}^{\text{+}}\text{,}{\text{Cl}}^{-}\text{,}{\text{Ag}}^{\text{+}}\text{,}\text{Ag,}{\text{Zn}}^{\text{2+}}\text{,}\text{Zn}\text{and}\text{Pb}$

Concept Introduction: The substances that get easily oxidized are reducing agent. They are on right side of the reduction half reactions. More negative standard reduction potential is better is reducing agent.

(c)

Interpretation Introduction

Interpretation: The species that can be oxidized by ${\text{SO}}_4{}^{2-}\left(aq\right)$ in acid needs to be determined.

Concept Introduction: The substance that can easily reduce is oxidizing agent. They are on left side of reduction half reactions. More positive standard reduction potential is better is reducing agent.

(d)

Interpretation Introduction

Interpretation: The species that can be reduced by Al (s) needs to be determined.

Concept Introduction: The substance that can easily reduce is oxidizing agent. They are on left side of reduction half reactions. More positive standard reduction potential is better is reducing agent.
