Chapter 6, Problem 45E

Interpretation Introduction

(a)

Interpretation:

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

Concept introduction:

The Latin system is an old method for naming metal cations which have two 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. For the lower ionic charge, the suffix “–ous” is used and for the the higher ionic charge, the suffix“–ic” is used.

Answer to Problem 45E

The Latin system name for ionic compound $\text{CuS}$ is cupric sulfide.

Explanation of Solution

The Latin name for the copper is cuprum. In ionic compound $\text{CuS}$, copper is present in higher oxidation state $\left(+2\right)$. Therefore, suffix “–ic” will be added to the Latin name of the copper. Therefore, ${\text{Cu}}^{+2}$ is named as cupric ion. The Latin system name for ionic compound $\text{CuS}$ is cupric sulfide.

Conclusion

The Latin system name for ionic compound $\text{CuS}$ is cupric sulfide.

Interpretation Introduction

(b)

Interpretation:

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

Concept introduction:

The Latin system is an old method for naming metal cations which have two 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”. For the lower ionic charge, the suffix “–ous” is used and for the the higher ionic charge, the suffix“–ic” is used.

Answer to Problem 45E

The Latin system name for ionic compound $\text{FeO}$ is ferrous oxide.

Explanation of Solution

The Latin name of iron is ferrum. In the ionic compound $\text{FeO}$, iron is present in lower oxidation state $\left(+2\right)$. Therefore suffix “–ous” will be added to the Latin name of iron. Therefore, ${\text{Fe}}^{+2}$ is named as ferrous ion.The Latin system name for ionic compound $\text{FeO}$ is ferrous oxide.

Conclusion

The Latin system name for ionic compound $\text{FeO}$ is ferrous oxide.

Interpretation Introduction

(c)

Interpretation:

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

Concept introduction:

The Latin system is an old method for naming metal cations which have two 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”. For the lower ionic charge, the suffix “–ous” is used and for the the higher ionic charge, the suffix“–ic” is used.

Answer to Problem 45E

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

Explanation of Solution

The Latin name of mercury is hydrargyrum or mercurum. In the ionic compound $\text{Hg}{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$, mercury is present in higher oxidation state $\left(+2\right)$. Therefore suffix “–ic” will be added to the Latin name of mercury. Therefore ${\text{Hg}}^{+2}$ is name as mercuric ion. The Latin system name for ionic compound $\text{Hg}{\left({\text{NO}}_{\text{2}}\right)}_{\text{2}}$ is mercuric nitrite.

Conclusion

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

Interpretation Introduction

(d)

Interpretation:

The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_2$ is to be stated.

Concept introduction:

The Latin system is an old method for naming metal cations which have two 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”. For the lower ionic charge, the suffix “–ous” is used and for the the higher ionic charge, the suffix“–ic” is used.

Answer to Problem 45E

The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_2$ is plumbous acetate.

Explanation of Solution

The Latin name of the lead is plumbum. In the ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_2$, lead is present in lower oxidation state $\left(+2\right)$. Therefore suffix “–ous” will be added to Latin name of the lead. Therefore, ${\text{Pb}}^{+2}$ is named as plumbous ion. The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_2$ is plumbous acetate.

Conclusion

The Latin system name for ionic compound $\text{Pb}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_2$ is plumbous acetate.
