The equivalent weight of iron in Fe(2)O ...

The equivalent weight of iron in `Fe_(2)O` would be:

A

28

B

56

C

18.6

D

112

Text Solution

Verified by Experts

The correct Answer is:
C
(c) `Fe_2O_3 rarr 2Fe` The change in O.N. of Fe is from +3 to 0. Hence equivalent weight of iron = 1/3 `xx `56 = 18.6
