The only cations present in slightly acidic solutions are `Fe^(3+)`,`Zn^(2+)` and `Cu^(2+)`. The reagent that when added in excess to this solution would identify and separate Feo in one step is

A

2M HCl

B

`6M NH_(3)`

C

6M NaOH

D

`H_(2)S`

Text Solution

Verified by Experts

`NH_(3)` forms soluble complex with `Zn^(2+)` and `Cu^(2+)`m leaving `Fe^(2+)`. Hence, (B) is the correct answer
