Chapter 18.8, Problem 18.12BFP

a)

Interpretation Introduction

Interpretation: To determine whether ${\text{FeBr}}_{\text{3}}$ is an acidic, basic, or neutral salt.

Concept introduction: Depending on the ability of the ion to react with water, the nature of the salt can be determined. If the cation is a strong base and the anion is a strong acid, then the solution or the salt will be neutral. If the cation is a weak base and the anion is a strong acid, then the solution will be acidic. If the cation is a strong base and the anion is a weak acid, then the solution will be basic.

(b)

Interpretation Introduction

Interpretation: To determine whether ${\text{Ca(NO}}_{\text{2}}{\text{)}}_{\text{2}}$ is an acidic, basic, or neutral salt.

Concept introduction: Depending on the ability of the ion to react with water, the nature of the salt can be determined. If the cation is a strong base and the anion is a strong acid, then the solution or the salt will be neutral. If the cation is a weak base and the anion is a strong acid then the solution will be acidic. If the cation is a strong base and the anion is a weak acid then the solution will be basic. Depending on the nature of the cation and the ion the nature of the solution can be determined.

c)

Interpretation Introduction

Interpretation: To determine whether ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_3\text{I}$ is an acidic, basic, or neutral salt.

Concept introduction: Depending on the ability of the ion to react with water the nature of the salt can be determined. If the cation is a strong base and the anion is a strong acid, then the solution or the salt will be neutral. If the cation is a weak base and the anion is a strong acid, then the solution will be acidic. If the cation is a strong base and the anion is a weak acid, then the solution will be basic.
