Chapter 9, Problem 86P

Interpretation Introduction

(a)

Interpretation:

Whether the aqueous solution of $\text{NaBr}$ is acidic, basic or neutral needs to be determined

Concept Introduction:

The reaction of an acid HA with a base BOH can be written as:

  $\text{HA + BOH}\text{}\underset{}{\to }{\text{ BA + H}}_{\text{2}}\text{O}$

Here BA stands for salt and the reaction named as neutralization reaction. Thus the reaction of an acid with a base results in the formation of salt and water. The salt is an ionic compound that is formed by the combination of the cation ( ${\text{B}}^{\text{+}}$ ) from base and anion ( ${\text{A}}^{\text{-}}$ ) from acid and forms salt BA. The $\text{pH}$ range of salts can be determined with the help of the strength of acid and base.

Acid	Base	Salt
Strong	Strong	Neutral
Strong	Weak	Acidic
Weak	Strong	Basic
Weak	Weak	Neutral
