Chapter 4, Problem 4.57P

Interpretation Introduction

Interpretation:

Whether the total ionic and net ionic equation is the same or different when $\text{Sr}{\left(\text{OH}\right)}_2$ reacts with ${\text{H}}_2{\mathrm{SO}}_4$ is to be determined.

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. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented.

An acid-base reaction is also known as neutralization reaction involves the reaction of acid and base. The water molecule is employed as the reactant as well as product unit in these reactions.

Spectator ions are the ions that are not a part of the actual chemical change but are present in the reaction mixture to balance the charge on both sides of the reaction. They are represented in the total ionic reaction. These are the dissolved ions present in the reaction mixture.
