Question

19. The equvalent weight of iron in
Fe2O3 would be​

Answer 1

Answer:

Equivalent weight definition: weight of substance requires to combine or displace 8−gram oxygen or 1−gram hydrogen.

One electron transfer is enough to displace and combine with hydrogen or oxygen

In Fe

2

O

3

The oxidation state of Fe in Fe

2

O

3

is +3.

It mean one third on Fe mole is enough to combine with 8−gram of O
