Chapter 5, Problem 5.79AP

(a)

Interpretation Introduction

Interpretation:

The oxidation and reduction species of the reaction and the half reaction of the given reaction has to be given.

The given reaction is,

  ${\text{Fe+Cu}}^{\text{2+}}\stackrel{}{\to }{\text{Fe}}^{\text{2+}}\text{+Cu}$

Concept introduction:

Oxidation and Oxidizing agent:

In the oxidation process, the electrons are lossed from an atom.  A compound that gains electrons during oxidation is known as oxidizing agent.

Reducing and Reducing agent:

Reduction is the gain of electrons by an atom and a compound that loses electrons during reduction is called as a reducing agent.

(b)

Interpretation Introduction

The oxidation and reduction species of the reaction and the half reaction of the given reaction has to be given.

The given reaction is,

  ${\text{Cl}}_{\text{2}}{\text{+2I}}^{\text{-}}\stackrel{}{\to }{\text{I}}_{\text{2}}{\text{+2Cl}}^{\text{-}}$

Concept introduction:

Refer to part (a).

(c)

Interpretation Introduction

The oxidation and reduction species of the reaction and the half reaction of the given reaction has to be given.

The given reaction is,

  ${\text{2Na+Cl}}_{\text{2}}\stackrel{}{\to }\text{2NaCl}$

Concept introduction:

Refer to part (a).
