Answer 2

Ferric oxide (Fe3O4) has oxidation state in the form of a fraction.

• Oxidation number or oxidation state of an element or ion gives the number of electrons that atom or ion should donate or accept in order to form a bond with another species.
• In ferrous oxide, the oxidation number of iron can be calculated as +3. Since 3 is a whole number, it is not the right answer.

2(Fe)+{3(-2)}=0

Fe= +3

• In ferrosoferric oxide, by using the above method we get oxidation state of Fe as. +2.
• In Fe3O4 however, we find the oxidation state of iron to be +8/3. This is the fractional oxidation state required.

3(Fe)+{4(-2)}=0

Fe= +8/3
