Chapter 9, Problem 73A

(a)

Interpretation Introduction

Interpretation: The name of the given acid should be determined.

Concept Introduction: Acids are substances that can donate ${\text{H}}^{\text{+}}$ ions in the solution. While naming acids the ending ‘ic’ is added to the root name and the suffix ‘acid’ is used.

Answer to Problem 73A

The name of the given acid is hydrochloric acid.

Explanation of Solution

The acid is comprised of hydrogen and chlorine, so the name of these elements is written followed by the suffix ‘acid’.

(b)

Interpretation Introduction

Interpretation: The name of the given acid should be determined.

Concept Introduction: Acids are substances that can donate ${\text{H}}^{\text{+}}$ ions in the solution. While naming acids the ending ‘ic’ is added to the root name and the suffix ‘acid’ is used.

Answer to Problem 73A

The name of the given acid is nitric acid.

Explanation of Solution

The acid is comprised of hydrogen ions and the nitrate ion, so the name of the acid is written by adding the ending ‘-ic’ to the root name nitrate by replacing the ‘e’. The suffix acid is also added.

(c)

Interpretation Introduction

Interpretation: The formula of the given acid should be determined.

Concept Introduction: Acids are substances that can donate ${\text{H}}^{\text{+}}$ ions in the solution. While naming acids the ending ‘ic’ is added to the root name and the suffix ‘acid’ is used.

Answer to Problem 73A

Sulfuric acid can be chemically represented as ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ .

Explanation of Solution

Sulfuric acid contains sulfate ions and two hydrogen ions, hence the formula is ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ .

(d)

Interpretation Introduction

Interpretation: The formula of the given acid should be determined.

Concept Introduction: Acids are substances that can donate ${\text{H}}^{\text{+}}$ ions in the solution. While naming acids the ending ‘ic’ is added to the root name and the suffix ‘acid’ is used.

Answer to Problem 73A

The chemical formula of acetic acid is ${\text{CH}}_{\text{3}}\text{COOH}$ .

Explanation of Solution

Acetic acid is a carboxylic acid containing two carbon atoms. It is formed when a carboxylic acid group is added to a methyl group.
