Chapter 9, Problem 92A

Interpretation Introduction

Interpretation:

The chemical and ionic equations need to be compared.

Concept introduction:

Chemical reaction is the actual process in which atoms of one or more substances rearrange to form new substances.

Explanation of Solution

Ionic equation and chemical equations are symbolic representation of chemical reaction. Chemical equation shows which substances are involved using chemical formulas of compounds and in case of ionic compound to show a reaction occurring between ions they utilize the dissociation of ionic compounds solution. Example, aqueous solution of sodium chloride and silver nitrate form sodium nitrate and silver chloride. For this reaction chemical equation is as follows:

${\text{AgNO}}_{\text{3}}\text{+NaCl}\to {\text{AgCl+NaNO}}_{\text{3}}$

For above reaction ionic equation is as follows:

${\text{Na}}^{\text{+}}+{\text{Cl}}^{-}+{\text{Ag}}^{\text{+}}+{\text{NO}}_3{}^{-}\to {\text{AgCl+Na}}^{\text{+}}{\text{+NO}}_3{}^{-}$

The net ionic equation will be:

${\text{Cl}}^{-}+{\text{Ag}}^{\text{+}}\to \text{AgCl}$
