Chapter 9, Problem 59A

(a)

Interpretation Introduction

Interpretation: Names of the given ion should be determined.

Concept Introduction: Monoatomic cations can be simply named by writing the name of the element followed by the word ‘ion’. Monoatomic anions are named by adding the suffix ‘ide’ to the root name of the element.

Answer to Problem 59A

The name of the given ion is barium ion.

Explanation of Solution

  ${\text{Ba}}^{\text{2+}}$ is a mono-atomic cation. The root name of the element is barium, hence the name of the ion is barium ion.

(b)

Interpretation Introduction

Interpretation: Names of the given ion should be determined.

Concept Introduction: Monoatomic cations can be simply named by writing the name of the element followed by the word ‘ion’. Monoatomic anions are named by adding the suffix ‘ide’ to the root name of the element.

Answer to Problem 59A

The given ion is an iodide ion.

Explanation of Solution

  ${\text{I}}^{-}$ is a mono-atomic anion. The root name of the element is iodine followed by the suffix ‘ide’, hence the name of the ion is iodide.

(c)

Interpretation Introduction

Interpretation: Names of the given ion should be determined.

Concept Introduction: Monoatomic cations can be simply named by writing the name of the element followed by the word ‘ion’. Monoatomic anions are named by adding the suffix ‘ide’ to the root name of the element.

Answer to Problem 59A

The given formula represents silver ions.

Explanation of Solution

The symbol Ag stands for silver, so the ion ${\text{Ag}}^{\text{+}}$ is named silver ion.

(d)

Interpretation Introduction
