Chapter U4, Problem 5RE

Interpretation Introduction

Interpretation: A neutralization reaction needs to be explained.

Concept Introduction: An acid is a species which donates hydrogen ions in the solution and a base is a species which donates hydroxide ions in the solution.

Explanation of Solution

A neutralization reaction takes place to neutralize acid and base to form salt and water. Here, reaction of acid and base takes place to form salt of conjugate base and acid and water.

This can be further explained by taking example of neutralization reaction of strong acid HCl and strong base NaOH.

The reaction can be represented as follows:

  $\text{HCl}\left(aq\right)+\text{NaOH}\left(aq\right)\to \text{NaCl}\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)$

In the above reaction, HCl and NaOH undergo neutralization reaction to form NaCl salt and water. This resultant solution has pH 7 that is for neutral in nature.
