Chapter 4, Problem 4.63P

(a)

Interpretation Introduction

Interpretation:

The number of moles of ${\mathrm{H}}^{+}$ ions that are present in $1.40\text{ L}$ of $0.25M$ perchloric acid is to be calculated.

Concept introduction:

Acid is a substance that dissociates in water to release ${\text{H}}^{+}$ ions. Depending upon the strength the acids can be classified into two types:

1. Strong acids

2. Weak acids

Strong acids are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release ${\text{H}}^{+}$ ions. They behave as strong electrolytes and conduct a large amount of electricity.

Weak acids are the substance that does not dissociates completely into its ions when dissolved in the solution. They dissociate partially in water to release ${\text{H}}^{+}$ ions. They behave as weak electrolytes and conduct less amount of electricity.

(b)

Interpretation Introduction

Interpretation:

The number of moles of ${\mathrm{H}}^{+}$ ions that are present in $6.8\text{ mL}$ of $0.92M$ nitric acid is to be calculated.
