Chapter 5, Problem 5.37AP

(a)

Interpretation Introduction

Interpretation:

The given reaction should be identified as whether precipitation, neutralization or redox reaction.

Concept introduction:

Reactions of ionic compounds can be grouped into three and they are,

1. 1. Precipitation reaction: A precipitation reaction takes place when two solutions of well soluble substances together form a poorly soluble salt.
2. 2. Acid- base neutralization reaction: it is a double displacement reaction in which an acid and a base react to form an ionic compound (salt) and water.
3. 3. Oxidation-reduction reaction: Both the oxidation and reduction reaction occurs together in a chemical reaction. It is also known as redox reaction.

Change in the oxidation number of atoms involved in the reaction is one of the special characteristic of reduction reaction.

The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.

Oxidation: Losing electrons, increasing oxidation number.

Reduction: Gaining electron, decreasing oxidation number.
