Chapter 15.1, Problem 15.1QAP

Interpretation Introduction

(a)

Interpretation:

Identify the following as an oxidation or a reduction reaction:

  ${\text{Al}}^{\text{3+}}\left(\text{aq}\right){\text{ + 3e}}^{\text{-}}\to \text{Al}\left(\text{s}\right)$

Concept Introduction:

Oxidation reaction is the gain of electrons and reduction reaction is the loss of electrons.

Interpretation Introduction

(b)

Interpretation:

Identify the following as an oxidation or a reduction reaction:

  $\text{Ca}\left(\text{s}\right)\to {\text{Ca}}^{\text{2+}}\left(\text{aq}\right){\text{ + 2e}}^{\text{-}}$

Concept Introduction:

Oxidation reaction is the gain of electrons and reduction reaction is the loss of electrons.

Interpretation Introduction

(c)

Interpretation:

Identify the following as an oxidation or a reduction reaction:

  ${\text{Fe}}^{\text{3+}}\left(\text{aq}\right){\text{+ e}}^{\text{-}}\to {\text{Fe}}^{\text{2+}}\left(\text{aq}\right)$

Concept Introduction:

Oxidation reaction is the gain of electrons and reduction reaction is the loss of electrons.
