Chapter 7, Problem 111A

Interpretation Introduction

(a)

Interpretation:

The ionic compound CaO should be named.

Concept introduction:

Nomenclature is the rule or system to create regular name for chemical compounds. Chemical compounds are made when two or more elements share electrons through covalent or ionic bond.

Answer to Problem 111A

Name of CaO is calcium oxide.

Explanation of Solution

In an ionic compound the elemental name of cation is name first and elemental name of anion is name last. Anion is given the stem of its elemental name + suffix-ide. Thus the name of CaO is calcium oxide.

(b)

Interpretation Introduction

Interpretation:

The ionic compound BaS should be named.

Concept introduction:

Nomenclature is the rule or system to create regular name for chemical compounds. Chemical compounds are made when two or more elements share electrons through covalent or ionic bond.

Answer to Problem 111A

Name of BaS is barium sulfide.

Explanation of Solution

In an ionic compound the elemental name of cation is name first and elemental name of anion is name last. Anion is given the stem of its elemental name + suffix-ide. Thus the name of BaS is barium sulfide.

(c)

Interpretation Introduction

Interpretation:

The ionic compound ${\text{AlPO}}_{\text{4}}$ should be named.

Concept introduction:

Nomenclature is the rule or system to create regular name for chemical compounds. Chemical compounds are made when two or more elements share electrons through covalent or ionic bond.

Answer to Problem 111A

The name of ${\text{AlPO}}_{\text{4}}$ is aluminium (III) phosphate.

Explanation of Solution

In an ionic compound the elemental name of cation is name first + to distinguish oxidation state a roman number and polyatomic anions is name last as its ionic name. Thus, the name of ${\text{AlPO}}_{\text{4}}$ is aluminium (III) phosphate.

(d)

Interpretation Introduction

Interpretation:

The ionic compound $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}$ should be named.

Concept introduction:

Nomenclature is the rule or system to create regular name for chemical compounds. Chemical compounds are made when two or more elements share electrons through covalent or ionic bond.

Answer to Problem 111A

The name of $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}$ is barium hydroxide.

Explanation of Solution

In an ionic compound the elemental name of polyatomic cation is name first plus and polyatomic anions is name last as its ionic name. Thus, the name of $\text{Ba}{\left(\text{OH}\right)}_{\text{2}}$ is barium hydroxide.

(e)

Interpretation Introduction

Interpretation:

The ionic compound $\text{Sr}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ should be named.

Concept introduction:

Nomenclature is the rule or system to create regular name for chemical compounds. Chemical compounds are made when two or more elements share electrons through covalent or ionic bond.

Answer to Problem 111A

The name of $\text{Sr}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ is strontium nitrate.

Explanation of Solution

In an ionic compound the elemental name of polyatomic ion and metal, cation is name first plus the elemental name of anions is name last as its ionic name. Thus, the name of $\text{Sr}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ is strontium nitrate.
