How to Write the Name for Fe(OH)3

In this video we'll write the correct name for Fe(OH)3. To write the name for Fe(OH)3 we’ll use the Periodic Table and follow some simple rules.

Because Fe(OH)3 has a polyatomic ion we’ll also need to use a table of names for common polyatomic ions, in addition to the Periodic Table.

--Keys for Naming Ternary Ionic Compounds--

1) Name the metal (the cation) as it appears on the Periodic Table.
     Na+ = Sodium       Mg2+ = Magnesium       Al3+ = Aluminum
2) Find the polyatomic ion on the Common Ion Table and write the name.

Note: It is possible to have two polyatomic ions such as NH4NO3. In this case find and write both names as found on the Common Ion Table.
