Given the standard oxidation potentials
`Fe overset(+0.4V)rarr Fe^(2+) (aq.) overset(-0.8V)rarr Fe^(3+) (aq.)`
`Fe overset(+0.9V)rarr Fe(OH)_(2) overset(0.6V)rarr Fe(OH)_(3)`
It is easier to oxidise `Fe^(2+) " to " Fe^(3+)in

A

acidic medium

B

alkaline medium

C

neutral medium

D

both in acidic and alkaline mediums

Text Solution

Verified by Experts

The correct Answer is:
B
`E_(Fe^(2+)//Fe^(3+))^(@)` is positive in alkaline solution, therefore, it is easier to oxidise `Fe^(2+) " to " Fe^(2+)` in alkaline medium
