Chapter 18.8, Problem 18.13BFP

a)

Interpretation Introduction

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

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 ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_{\text{3}}{\text{NO}}_{\text{2}}$ is acidic, basic, or neutral.
