Chapter 4, Problem 4.34E

Interpretation Introduction

(a)

Interpretation:

The name of the given binary ionic compounds is to be stated by using a Roman numeral.

Concept introduction:

Ionic compounds are those compounds that have the strong electrostatic force of attraction between the oppositely charged ions. The binary ionic compounds are composed of only one cation and one anion.

The naming of non-metal ions is done by the addition of suffix –ide at the end of the element’s name. The naming of binary ionic compound is represented by the name of metal followed by the name of non-metal.

Answer to Problem 4.34E

The name of the binary ionic compound $\text{PbO}$ is plumbous oxide and ${\text{PbO}}_2$ is plumbic oxide.

Explanation of Solution

The non-English names are used to indicate the lower and higher ionic charges of the metal ion. The ending $\text{-}ous$ is added to an ion that has lower charge and $\text{-}ic$ is added to an ion that has higher charge.

The binary ionic compounds are $\text{PbO}$ and ${\text{PbO}}_2$. Both the compounds contain lead as a metal and oxygen as a non-metal. The lead can exists as ${\text{Pb}}^{2+}$ and ${\text{Pb}}^{4+}$ ions and oxygen as ${\text{O}}^{2-}$ ion in ionic form.

The non-English root for lead $\left(\text{Pb}\right)$ is $plumb\text{-}$. The endings $\text{-}ous$ is used for ${\text{Pb}}^{2+}$ while endings $\text{-}ic$ is used for ${\text{Pb}}^{4+}$. The suffix –ide is added after “ox” of oxygen to obtain oxide.

Hence, the name of the binary ionic compound $\text{PbO}$ is plumbous oxide and ${\text{PbO}}_2$ is plumbic oxide.

Conclusion

The name of the binary ionic compound $\text{PbO}$ is plumbous oxide and ${\text{PbO}}_2$ is plumbic oxide.

Answer to Problem 4.34E

The name of the binary ionic compound $\text{CuCl}$ is cuprous chloride and ${\text{CuCl}}_2$ is cupric chloride.

Explanation of Solution

The non-English names are used to indicate the lower and higher ionic charges of the metal ion. The ending $\text{-}ous$ is added to an ion that has lower charge and $\text{-}ic$ is added to an ion that has higher charge.

The binary ionic compounds are $\text{CuCl}$ and ${\text{CuCl}}_2$. Both the compounds contain copper as a metal and chlorine as a non-metal. The copper can exists as ${\text{Cu}}^{+}$ and ${\text{Cu}}^{+2}$ ions and chlorine as ${\text{Cl}}^{-}$ ion in ionic form.

The endings $\text{-}ous$ is used for ${\text{Cu}}^{+}$ while endings $\text{-}ic$ is used for ${\text{Cu}}^{+2}$. The suffix –ide is added to “chlor” of chlorine to obtain chloride.

Hence, the name of the binary ionic compound $\text{CuCl}$ is cuprous chloride and ${\text{CuCl}}_2$ is cupric chloride

Conclusion

The name of the binary ionic compound $\text{CuCl}$ is cuprous chloride and ${\text{CuCl}}_2$ is cupric chloride.

Answer to Problem 4.34E

The name of the binary ionic compound ${\text{Au}}_{\text{2}}\text{S}$ is aurous sulfide and ${\text{Au}}_{\text{2}}{\text{S}}_3$ is auric sulfide.

Explanation of Solution

The non-English names are used to indicate the lower and higher ionic charges of the metal ion. The ending $\text{-}ous$ is added to an ion that has lower charge and $\text{-}ic$ is added to an ion that has higher charge.

The given binary ionic compounds are ${\text{Au}}_{\text{2}}\text{S}$ and ${\text{Au}}_{\text{2}}{\text{S}}_3$. Both the compounds contain gold as a metal and sulfur as a non-metal. The gold exists as ${\text{Au}}^{+}$ and ${\text{Au}}^{3+}$ ions and sulfide as ${\text{S}}^{2-}$ ion in ionic form.

The non-English root for gold $\left(\text{Au}\right)$ is $aur\text{-}$. The endings $\text{-}ous$ is used for ${\text{Au}}^{+}$ while endings $\text{-}ic$ is used for ${\text{Au}}^{3+}$. The suffix –ide is added after “sulf” of sulfur to obtain sulfide.

Hence, the name of the binary ionic compound ${\text{Au}}_{\text{2}}\text{S}$ is aurous sulfide and ${\text{Au}}_{\text{2}}{\text{S}}_3$ is auric sulfide.

Conclusion

The name of the binary ionic compound ${\text{Au}}_{\text{2}}\text{S}$ is aurous sulfide and ${\text{Au}}_{\text{2}}{\text{S}}_3$ is auric sulfide.

Answer to Problem 4.34E

The name of the binary ionic compound $\text{CoO}$ is cobaltous oxide and ${\text{Co}}_2{\text{O}}_3$ is cobaltic oxide.

Explanation of Solution

The non-English names are used to indicate the lower and higher ionic charges of the metal ion. The ending $\text{-}ous$ is added to an ion that has lower charge and $\text{-}ic$ is added to an ion that has higher charge.

The binary ionic compounds are $\text{CoO}$ and ${\text{Co}}_2{\text{O}}_3$. Both the compounds cobalt as a metal and oxygen as a non-metal. The cobalt exists as ${\text{Co}}^{2+}$ and ${\text{Co}}^{3+}$ ions and oxygen as ${\text{O}}^{2-}$ ions in ionic form.

The endings $\text{-}ous$ is used for ${\text{Co}}^{2+}$ while endings $\text{-}ic$ is used for ${\text{Co}}^{3+}$. The suffix –ide is added after “ox” of oxygen to obtain oxide.

Hence, the name of the binary ionic compound $\text{CoO}$ is cobaltous oxide and ${\text{Co}}_2{\text{O}}_3$ is cobaltic oxide

Conclusion

The name of the binary ionic compound $\text{CoO}$ is cobaltous oxide and ${\text{Co}}_2{\text{O}}_3$ is cobaltic oxide.
