Chapter 9.4, Problem 38SP

(a)

Interpretation Introduction

Interpretation: The formula of the given acids is to be stated.

Concept Introduction: Acids are the species that sour in taste. They contain ${\text{H}}^{+}$ ions and the type of an acid depends on the number of hydrogen ions. They turn blue litmus to red.

Answer to Problem 38SP

The formula of the acid is ${\text{HClO}}_4$ .

Explanation of Solution

The given acid is perchloric acid. It is composed of ${\text{H}}^{+}$ and ${\text{ClO}}_4{}^{-}$ . Thus, the formula of the acid is ${\text{HClO}}_4$ .

(b)

Interpretation Introduction

Concept Introduction: Acids are the species that sour in taste. They contain ${\text{H}}^{+}$ ions and the type of an acid depends on the number of hydrogen ions. They turn blue litmus to red.

Answer to Problem 38SP

The formula of the acid is $\text{HI}$ .

Explanation of Solution

The given acid is hydroiodic acid. It is composed of ${\text{H}}^{+}$ and ${\text{I}}^{-}$ . Thus, the formula of the acid is $\text{HI}$ .

(c)
