Chapter 12, Problem 97A

(a)

Interpretation Introduction

Interpretation: ${\text{SiO}}_2$ substance is to be named.

Concept Introduction: When naming a compound, the cation is always named first, then the anion with a modified −ide suffix.

Answer to Problem 97A

The name of ${\text{SiO}}_2$ is silicone oxide.

Explanation of Solution

The substance ${\text{SiO}}_2$ contains silicon cation $\left({\text{Si}}^{\text{4+}}\right)$ and oxide anion $\left({\text{O}}^{\text{2-}}\right)$ . Therefore, the name of ${\text{SiO}}_2$ is silicon oxide.

(b)

Interpretation Introduction

Interpretation: ${\text{K}}_2{\text{SO}}_4$ substance is to be named.

Concept Introduction: When naming a compound, the cation is always named first, then the anion with a modified −ide suffix.

Answer to Problem 97A

The name of ${\text{K}}_2{\text{SO}}_4$ is Potassium sulfate.

Explanation of Solution

The substance ${\text{K}}_2{\text{SO}}_4$ contains potassium cation $\left({\text{K}}^{\text{+}}\right)$ and sulfate anion $\left({\text{SO}}_4^{2-}\right)$ . Therefore, the name of ${\text{K}}_2{\text{SO}}_4$ is potassium sulfate.

(c)

Interpretation Introduction

Interpretation: ${\text{H}}_2{\text{CO}}_3$ substance is to be named.

Concept Introduction: When naming a compound, the cation is always named first, then the anion with a modified −ide suffix.

Answer to Problem 97A

The name of ${\text{H}}_2{\text{CO}}_3$ is carbonic acid.

Explanation of Solution

The substance ${\text{H}}_2{\text{CO}}_3$ contains hydrogen cation $\left({\text{H}}^{\text{+}}\right)$ and carbonate anion $\left({\text{CO}}_3^{2-}\right)$ . Therefore, the name of ${\text{H}}_2{\text{CO}}_3$ is carbonic acid.

(d)

Interpretation Introduction

Interpretation: $\text{MgS}$ substance is to be named.

Concept Introduction: When naming a compound, the cation is always named first, then the anion with a modified −ide suffix.

Answer to Problem 97A

The name of $\text{MgS}$ is magnesium sulfide.

Explanation of Solution

The substance $\text{MgS}$ contains magnesium cation $\left({\text{Mg}}^{\text{2+}}\right)$ and sulfide anion $\left({\text{S}}^{\text{2-}}\right)$ . Therefore, the name of $\text{MgS}$ is magnesium sulfide.
