Question

The equivalent weight of `FeC_(2)O_(4)` in the change
`FeC_(2)O_(4)rarrFe^(3+)+CO_(2)` is
A. `M`
B. `M//2`
C. `M//3`
D. `2M//3`

Answer 1

Correct Answer - C
`underset(+2)(Fe)underset(+3)(C_(2)O_(4)) rarr underset(+3)(Fe^(+3))+underset(+4)(CO_(2))`
Total change in oxidation:
`1xx1+2xx1=3`
Eq. wt. `=(M)/(3)`
