In a reaction, the ferrous `(Fe^(+ +))` iron is oxidised to ferric `(FE^(+ +))` ion. The equivalent weight of the ion in the avbove reaction is equal to

Options

A. The atlic weight
B. `1//5` of the atomic weight
C. Half of the atomic weight
D. Twice the atomic weight

Answer

A

Explanation

The atomic weight,
Equivalent weight `= ("Atomic weight")/("No . of" e^(-) "lost or gaied")`
`Fe^(2+) rarr Fe^(3+) + e^(-)`
`:.` Equivalent weight = Atomic weight
