The Oxidation State of Fe in Fe3O4

Fe3O4, also known as magnetite, is an iron oxide compound consisting of three iron (Fe) atoms and four oxygen (O) atoms. The oxidation state of an element refers to the charge it carries when it forms a compound or ion. In the case of Fe3O4, the oxidation state of iron can be determined by considering the overall charge of the compound and the known oxidation states of oxygen.

1. Oxidation States of Oxygen:
Oxygen generally has an oxidation state of -2 in most compounds. Since there are four oxygen atoms in Fe3O4, the total negative charge contributed by oxygen is -8.

2. Overall Charge of Fe3O4:
To determine the oxidation state of iron in Fe3O4, we need to consider the overall charge of the compound. Fe3O4 is a neutral compound, which means the sum of the charges must be zero.

3. Calculating the Oxidation State of Iron:
Since the overall charge of Fe3O4 is zero, the sum of the oxidation states of iron must balance the -8 charge contributed by oxygen.

Let's assume the oxidation state of iron in Fe3O4 is x.

- Multiply the oxidation state of iron by the number of iron atoms (3) to get the total charge contributed by iron: 3x.
- Add the total charge contributed by iron (3x) to the total negative charge contributed by oxygen (-8) to get the overall charge of the compound.
- Set the overall charge equal to zero: 3x + (-8) = 0.
- Simplify the equation: 3x = 8.
- Solve for x: x = 8/3.

So, the oxidation state of iron (Fe) in Fe3O4 is +8/3, or we can say it is +8/3 per iron atom.

Conclusively, the oxidation state of iron in Fe3O4 is +8/3.
