Question

86. One mole of iron (55.8 gm), when oxidised to +2oxidation state gives up :(1) 1N, electron (2) 2N electron(3) 3N, electron(4)0.5 mole of electron​

Answer 1

Explanation:

Please find below the solution to the query posted by you.

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

F1 mole −→−−− Fe2+1 mol + 2 e−2 mol

From the reaction, it is evident that, one mole of Fe gives two moles electrons on oxidation to Fe2+.

We know that,

1 mol = NA

2 mol of electrons = 2 NA

1 mol Fe releases 2 NA electrons on oxidation to Fe2+.

Hope this information will clear your doubt regarding oxidation reactions.
