Chapter 12, Problem 58P

Interpretation Introduction

Interpretation:

In the reaction that involves the conversion of aluminum oxide to aluminum chloride, the oxidation state of aluminum must be identified through a balanced chemical reaction.

Concept Introduction:

• Chemical reactions in which both reduction and oxidation reactions take place are called redox reactions. These involve changes in the oxidation state of the reactants.
• Reduction reactions proceed via gain of electrons and a decrease in the oxidation number. In contrast, oxidation reactions proceed via loss of electrons and an increase in the oxidation number.
• An oxidizing agent is an electron acceptor, i.e. it gains electrons and undergoes reduction. A reducing agent is an electron donor, i.e. it loses electrons and gets oxidized.
