19. The equvalent weight of iron inFe2O3 would be |
|
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 oxygenIn 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 2 THEREFORE, the equivalent weight of iron in Fe 2 O 3 = 355.8 =18.6 G |
