Question

oxidation number of Fe in Fe2(so4)3

Answer 1

Answer:

Oxidation number of Fe in Fe₂(SO₄)₃ is +3

Explanation:

We know that charge on SO₄ is -2

Le the oxidation number Fe be x

Then

2x + (-2) × 3 = 0

or, 2x = 6

or, x = 3

Therefore, the oxidation number of Fe in Fe₂(SO₄)₃ is +3

Alternatively if the formula of a compound is $A_xB_y$ then the oxidation number of A is +y while that of B is -x. From this also we can see that the oxidation number of Fe is +3

Answer 2

oxidation number of Fe in Fe2(so4)3 is +3
