Chapter 4, Problem 4.37P

Interpretation Introduction

Interpretation:

The two sets of equations (both molecular and total ionic) with different reactants that have the same net ionic equation as the following equation is to be determined.

$\text{Ba}{\left({\text{NO}}_3\right)}_2\left(aq\right)+{\text{ Na}}_2{\text{CO}}_3\left(aq\right)\to {\text{BaCO}}_3\left(s\right)+2{\text{NaNO}}_3\left(aq\right)$

Concept introduction:

There are three types of equations that are utilized to represent an ionic reaction:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The molecular equation represents the reactants and products of the ionic reaction in undissociated form. A solid product is formed in the reaction. In total ionic reaction, all the soluble substances that are present in the reaction mixture are dissociated into ions and in net ionic reaction, the useful ions that participate in the reaction are represented.
