Question

What quantity of electron if lost when one mole of iron (ii) irons is oxidized to iron(iii) irons

Answer 1

Answer:

The oxidation reaction of Fe to Fe2+ can be written as

                 Fe⟶Fe2++2e−

            1 mol       1 mol    2 mol

From the reaction, it is evident that, one mole of Fe gives two moles electrons on oxidation toFe2+.

We know that,       1 mol=NA

2 mol of electrons=2 NA

1 mol Fe releases 2 NA electrons on oxidation toFe2+.
