Chapter 6, Problem 46E

Interpretation Introduction

(a)

Interpretation:

The Latin system name for ionic compound ${\text{Cu}}_2\text{S}$ is to be stated.

Concept introduction:

The Latin system is an older method for naming metal cations which have two common ionic charges. The Latin system is also known as the suffix system because this system uses the Latin name of the metal and applies the suffix -ous or -ic. The lower ionic charge applies an -ous suffix and the higher ionic charge applies an -ic suffix.

Answer to Problem 46E

The Latin system name for ionic compound ${\text{Cu}}_2\text{S}$ is cuprous sulfide.

Explanation of Solution

The Latin name for the copper is cuprum. In ionic compound ${\text{Cu}}_2\text{S}$, copper is in $+1$ oxidation state. Therefore, suffix -ous is added to the Latin name of the copper. Therefore, ${\text{Cu}}^{+}$ is named as cuprous ion. Therefore, the Latin system name for ionic compound ${\text{Cu}}_2\text{S}$ is cuprous sulfide.

Conclusion

Cuprous sulfide is the Latin name of ${\text{Cu}}_2\text{S}$.

Interpretation Introduction

(b)

Interpretation:

The Latin system name for ionic compound ${\text{Fe}}_2{\text{O}}_3$ is to be stated.

Concept introduction:

The Latin system is an older method for naming metal cations which have two common ionic charges. The Latin system is also known as the suffix system because this system uses the Latin name of the metal and applies the suffix -ous or -ic. The lower ionic charge applies an -ous suffix and the higher ionic charge applies an -ic suffix.

Answer to Problem 46E

The Latin system name for ionic compound ${\text{Fe}}_2{\text{O}}_3$ is ferric oxide.

Explanation of Solution

The Latin name of iron is ferrum. In the ionic compound ${\text{Fe}}_2{\text{O}}_3$, iron is in $+3$ oxidation state. Therefore suffix -ic is added to the Latin name of iron. Therefore, ${\text{Fe}}^{3+}$ is named as ferric ion. Therefore the Latin system name for ionic compound ${\text{Fe}}_2{\text{O}}_3$ is ferric oxide.

Conclusion

Ferric oxide is the Latin name of ${\text{Fe}}_2{\text{O}}_3$.

Interpretation Introduction

(c)

Interpretation:

The Latin system name for ionic compound ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is to be stated.

Concept introduction:

The Latin system is an older method for naming metal cations which have two common ionic charges. The Latin system is also known as the suffix system because this system uses the Latin name of the metal and applies the suffix -ous or -ic. The lower ionic charge applies an -ous suffix and the higher ionic charge applies an -ic suffix.

Answer to Problem 46E

The Latin system name for ionic compound ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercurous nitrite.

Explanation of Solution

The Latin name of mercury is hydrargyrum or mercurum. In the ionic compound ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$, mercury is in $+1$ oxidation state. Therefore suffix –ous is added to the Latin name of mercury. Therefore ${\text{Hg}}^{+}$ is name as mercurous ion. Therefore, the Latin system name for ionic compound ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercurous nitrite.

Conclusion

Mercurous nitrite is the Latin name of ${\text{Hg}}_2{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$.

Interpretation Introduction

(d)

Interpretation:

The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is to be stated.

Concept introduction:

The Latin system is an older method for naming metal cations which have two common ionic charges. The Latin system is also known as the suffix system because this system uses the Latin name of the metal and applies the suffix -ous or -ic. The lower ionic charge applies an -ous suffix and the higher ionic charge applies an -ic suffix.

Answer to Problem 46E

The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is plumbic acetate.

Explanation of Solution

The Latin name of the lead is plumbum. In the ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$, lead is in $+4$ oxidation stat. Therefore suffix -ic is added to Latin name of the lead. Therefore, ${\text{Pb}}^{4+}$ is named as plumbic ion. Therefore, the Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$ is plumbic acetate.

Conclusion

Plumbic acetate is the Latin name of $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_4$.
