Chapter 7, Problem 10DQ

Interpretation Introduction

Interpretation:The acidic or basic nature of anion formed when a certain sodium compound is dissolved in water to liberate ${\mathrm{Na}}^{+}$ ion needs to be explained. Also, comprehend the simultaneous nature of anion as an acid and a base.

Concept Introduction: An acid is the substance that gives H+ or ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ ions in its aqueous solution. A base is the substance that gives ${\text{OH}}^{-}$ ions in its aqueous solution.

The reaction of acid and base results the formation of salt and water. The reaction is known as neutralization reaction or acid-base reaction and can be written as:

  ${\text{HA}}_{\text{(aq)}}{\text{ + BOH}}_{\text{(aq) }}\stackrel{}{\to }{\text{H}}_{\text{2}}{\text{O}}_{\text{(l)}}{\text{+ BA}}_{\text{(aq)}}$

Here, BA stands for salt and BOH for base.
