Chapter 19.4, Problem 39LC

Interpretation Introduction

Interpretation : The products of a reaction between an acid and a base are to be reviewed.

Concept Introduction : Acids are substances that contain hydrogen and ionize to produce hydrogen ions $\left({\text{H}}^{\text{+}}\right)$ in an aqueous solution. Bases are substances that ionize in aqueous solutions to produce hydroxide ions $\left({\text{OH}}^{-}\right)$ .

Answer to Problem 39LC

The products of a reaction between an acid and a base are its respective salt and water.

Explanation of Solution

When the bases and acids react, they form salt and water.

A strong acid and strong base react completely to form a neutral solution.

A neutralization reaction is a name for this kind of reaction.

The general word equation for the neutralization reaction is given as

  $\text{Acid}\text{+}\text{Base}\to \text{Salt}\text{+}\text{Water}$

Consider the acid-base reaction that takes place between hydrochloric acid and sodium hydroxide giving sodium chloride salt and water.

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

When there are an equal number of hydrogen ions and hydroxide ions in the solution, the reaction between an acid and a base will be completed.

The mole ratio of the above reaction is $1:1$ .
