When metallic aluminum is added to a solution containing iron (ii) sulfate a reaction occurs. what species is being oxidized in the overall reaction? when metallic aluminum is added to a solution containing iron (ii) sulfate a reaction occurs. what species is being oxidized in the overall reaction? fe2 + (aq) so42 - (aq) al (s) al3 + (aq) ?

The Balance equation is as follow,

2 Al + 3 FeSO ₄ → Al₂ (SO₄) ₃ + 3 Fe

Oxidation Number of elements in reactants,

Al = 0

Fe = + 2

SO ₄ = - 2

Oxidation Number of elements in products,

Al = = 3

Fe = 0

SO₄ = - 2

Result:

As the oxidation state of Al has changed from 0 to + 3, means it has lost 3 electrons so it is oxidized.

And the oxidation state of Fe has changed from + 2 to 0, so it has gained 2 electrons, hence it is reduced.
