Chapter 6, Problem 34E

Interpretation Introduction

(a)

Interpretation:

The systematic name of ${\text{Cu}}_2{\text{SO}}_{\text{4}}$ using stock system is to be stated.

Concept introduction:

Ternary compounds are those ionic compounds that contain metal ions connected to two other elements. They have a monoatomic metal cation and an oxyanion; that is, polyatomic in their formula. In the chemical formula of ternary compounds, the cation is present before the anion. They are named by adding the suffixes -ate and –ite.

In the stock system, the oxidation number of the metal cation is written in Roman numbers within parenthesis.

Answer to Problem 34E

The systematic name of ${\text{Cu}}_2{\text{SO}}_{\text{4}}$ is copper (I) sulfate.

Explanation of Solution

The ternary ionic compound, ${\text{Cu}}_2{\text{SO}}_{\text{4}}$, has copper (I) ion and the sulfate ion in its formula. Copper (I) is a monoatomic metal cation, and sulfate ion is a polyatomic oxyanion. Therefore, the name of ${\text{Cu}}_2{\text{SO}}_{\text{4}}$ is copper (I) sulfate.

Conclusion

The systematic name of ${\text{Cu}}_2{\text{SO}}_{\text{4}}$ is copper (I) sulfate.

Interpretation Introduction

(b)

Interpretation:

The systematic name of ${\text{Fe}}_2{\left({\text{CrO}}_{\text{4}}\right)}_3$ using stock system is to be stated.

Answer to Problem 34E

The systematic name of ${\text{Fe}}_2{\left({\text{CrO}}_{\text{4}}\right)}_3$ is iron (III) chromate.

Explanation of Solution

The ternary ionic compound, ${\text{Fe}}_2{\left({\text{CrO}}_{\text{4}}\right)}_3$, has iron (III) ion and chromate ion in its formula. Iron (III) is a monoatomic metal cation, and chromate ion is a polyatomic oxyanion. Therefore, the name of ${\text{Fe}}_2{\left({\text{CrO}}_{\text{4}}\right)}_3$ is iron (III) chromate.

Conclusion

The systematic name of ${\text{Fe}}_2{\left({\text{CrO}}_{\text{4}}\right)}_3$ is iron (III) chromate.

Interpretation Introduction

(c)

Interpretation:

The systematic name of ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ using stock system is to be stated.

Concept introduction:

In the chemical formula of ternary compounds, the cation is present before the anion. They are named by adding the suffixes -ate and –ite.

In the stock system, the oxidation number of the metal cation is written in Roman number within parenthesis.

Answer to Problem 34E

The systematic name of ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercury (I) nitrite.

Explanation of Solution

The ternary ionic compound, ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$, has mercury (I) ion and the nitrite ion in its formula. Mercury (I) ion is a monoatomic metal cation, and nitrite ion is a polyatomic oxyanion. Therefore, the name of ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercury (I) nitrite.

Conclusion

The systematic name of ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercury (I) nitrite.

Interpretation Introduction

(d)

Interpretation:

The systematic name of $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ using stock system is to be stated.

Concept introduction:

Ternary compounds are those ionic compounds that contain metal ions connected to two other elements. They have a monoatomic metal cation and an oxyanion; that is, polyatomic in their formula. In the chemical formula of ternary compounds, the cation is present before the anion. They are named by adding suffix-ate and –ite.

In the stock system, the oxidation number of the metal cation is written in Roman number within parenthesis.

Answer to Problem 34E

The systematic name of $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is lead (IV) acetate.

Explanation of Solution

The ternary ionic compound, $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$, has lead (IV) ion and the acetate ion in its formula. Lead (IV) ion is a monoatomic metal cation, and acetate ion is a polyatomic oxyanion. Therefore, the name of $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is lead (IV) acetate.

Conclusion

The systematic name of $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is lead (IV) acetate.
