Chapter 4, Problem 4.133P

(a)

Interpretation Introduction

Interpretation:

The balanced molecular, total ionic, and net ionic equations of sulphuric acid and hydroxide reaction is to be determined.

Concept introduction:

Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociates completely in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

Weak acids and weak bases are the substance that do not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

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

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 reaction are represented.

(b)

Interpretation Introduction

The moles of acid $\left({\text{H}}_{\text{2}}{\text{SO}}_4\right)$ and of base $\left(\text{NaOH}\right)$ that reacted is to be determined.

Concept introduction:

Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociates completely in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

Weak acids and weak bases are the substance that do not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release ${\text{H}}^{+}$ ions and ${\text{OH}}^{-}$ ions.

Interpretation Introduction

The molarity of the acid $\left({\text{H}}_{\text{2}}{\text{SO}}_4\right)$ and of base $\left(\text{NaOH}\right)$ is to be determined.
