Question

onic compounds typically result from bonding between metals and nonmetals. Metals are usually the cation and nonmetals the anion. These compounds are named using the cation first such as magnesium (Mg) and the anion second such as Cl with an -ide attached to its name. MgCl2 would be pronounced magnesium chloride. Some cations have the possibility of different ionic states such as Fe which can exist as Fe2+ or Fe3+. The state of cation is indicated using a roman numeral in parentheses such as Fe203 would be iron(III)oxide. Provide an example of each of the following giving both the molecular formula and the written name.

1.) Binary ionic compound containing a metal that forms only one type of cation.

2.) Binary ionic compound containing a metal that forms more than one type of cation.

3.) An ionic compound containing a polyatomic ion (cation or anion).

4.) A hydrated ionic compound.

Explanation / Answer

1) binary ionic compounds is NaCl ( sodium chloride) which has a Na+ cation.

2)  binary ionic compounds are as FeCl2 ( ferrous chloride)  and FeCl3 ( ferric chloride) have cation such as Fe2+ and Fe3+

3) sodium phosphate is Na3PO4 which contains an polyatomic anion PO4^3-

4) Cobalt(II) chloride hexahydrate is CoCl2•6H2O which is a hydrated ionic compound.
