Question

24. Oxidation state of Fe in Fe2O4 is
1 1
2²2
(1)
m
(2) +2, +3
is
(3) +2
(4) +4, +2​

Answer 1

Fe3O4 contains both Fe2O3 and FeO in it.

For Fe2O3:

Let oxidation state of Fe be x.

=> 2*x -2*3 = 0

=> 2x = 6

=> x = +3

=>Hence, the oxidation state of Fe in Fe2O3 is +3.

For FeO:

Let oxidation state of Fe be y.

=> y - 2 = 0

=> y = +2

=> Hence, the oxidation state of Fe in FeO is +2.

So, in Fe3O4 (Fe2O3.FeO).

The oxidation states of Iron are + 2 and  + 3.

So, the correct answer is (2) +2 , +3.

Answer 2

Answer:

Oxidation state of Fe in Fe2O4 is +2,+3.

Explanation:

• The amount of electrons an atom gains or loses when it interacts with another species outside of its outermost shell is what is meant by the term "oxidation state" of an atom.
• Even if it forms a covalent bond, an atom with a higher electronegativity is given a negative oxidation state.
• Fe2O4 has a molecular weight of 175.688.
• Iron has two oxidation states for the following reasons: -Since iron has an atomic number of 26 and an electronic configuration of [Ar]3d64s2, it will exhibit both a +2 and a +3 oxidation state to achieve stability.
