Chapter 4, Problem 4.121EP

(a)

Interpretation Introduction

Interpretation:

The name of the ionic compound formed from the ions Al3+ and CO32- is to be written.

Concept Introduction:

Chemical formulas and names for ionic compounds containing polyatomic ions:

Ionic compounds containing positive and negative charges present must add to zero.

If more than one polyatomic ion is present in a compound, the chemical formula can be written as a polyatomic ion is enclose in parentheses and a subscript, placed outside of the parentheses.  Example- Fe(OH)3.

Sometimes same element is present in two different locations.  For example, NH4NO3- in this chemical formula “N” is present in two different locations as NH4+ and NO3- ions.

Answer to Problem 4.121EP

The name of the ionic compound formed from the ions Al3+ and CO32- is Aluminium carbonate.

Explanation of Solution

The given name of the compound has Al3+ and CO32- ions.

Aluminium ion has +3 charge and carbonate ion has -2 charge.  So, 2:3 ratio of aluminium and carbonate ion produces a chemical formula Al2(CO3)3 with zero total charge.

Hence, the chemical formula of the compound is Al2(CO3)3.

The metal atom is aluminium cation and polyatomic anion is carbonate ion.

Hence, the name of the compound Al2(CO3)3 is aluminium carbonate.

Answer to Problem 4.121EP

Three polyatomic ions present in the ionic compound formed from the ions Al3+ and CO32-.

Explanation of Solution

The given name of the compound has Al3+ and CO32- ions.

Aluminium ion has +3 charge and carbonate ion has -2 charge.  So, 2:3 ratio of aluminium and carbonate ion produces a chemical formula Al2(CO3)3 with zero total charge.

The chemical formula of the compound is Al2(CO3)3.

Dissociation of Al2(CO3)3 is as follows.

    Al2(CO3)3  2Al3++ 3CO32-

From the above reaction, one formula unit of aluminium carbonate (Al2(CO3)3) produces two monoatomic ions (Al3+) and three polyatomic ions (CO32-).

Hence, three polyatomic ions present in the ionic compound formed from the ions Al3+ and CO32-

Answer to Problem 4.121EP

Two monoatomic ions present in the ionic compound formed from the ions Al3+ and CO32-.

Explanation of Solution

The given name of the compound has Al3+ and CO32- ions.

Aluminium ion has +3 charge and carbonate ion has -2 charge.  So, 2:3 ratio of aluminium and carbonate ion produces a chemical formula Al2(CO3)3 with zero total charge.

The chemical formula of the compound is Al2(CO3)3.

Dissociation of Al2(CO3)3 is as follows.

    Al2(CO3)3  2Al3++ 3CO32-

From the above reaction, one formula unit of aluminium carbonate (Al2(CO3)3) produces two monoatomic ions (Al3+) and three polyatomic ions (CO32-).

Hence, two monoatomic ions present in the ionic compound formed from the ions Al3+ and CO32-
