1 mol of `FeSO_(4)` (atomic weight of Fe is 55.84 g `mol^(-1)`) is oxidised to `Fe_(2)(SO_(4))_(3)`. Calculate the equivalent weight of ferrous ion

A

`55.84`

B

`27.92`

C

`18.61`

D

`111.68`

Text Solution

Verified by Experts

The correct Answer is:
A
Atomic mass of Fe= 55.84
`because` Equivalent mass `=("Atomic mass")/("Change in oxidation state")`
For the charge, `Fe^(2+) rarr Fe^(3+)` i.e `(3-2=1)`
the equivalent mass `=(55.84)/(1)=55.84`
