Determine the name of the following compound Fe(OH) 3 , Provide explanation of how you determined the name, including the type o
stepan [7]

Answer:

1. Iron(iii) hydroxide

2. It is a base

Explanation:

To determine the name of the compound, we must find the oxidation number Fe in the compound since the oxidation number of O is —2 in all its compound except for peroxide where it —1 and the oxidation number of Hydrogen is always +1 in all its compounds except for hydrides where it is —1. The oxidation number of Fe can calculated as follows:

Fe(OH)3 = 0

O = —2

H = +1

Fe =?

Fe + 3( —2 + 1) = 0

Fe + 3(—1) = 0

Fe —3 = 0

Fe = 3

The oxidation number of Fe in Fe(OH)3 is 3.

Therefore, the name of Fe(OH)3 is Iron(iii) hydroxide

Fe(OH)3 is a base since it contains the OH group
