`Fe(OH)_(3)` and `Cr(OH)_(3)` precipitates can be completely separated by `:`

A

`Aq.NH_(3)`

B

`HCl`

C

`NaOH//H_(2)O_(2)`

D

`H_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Both dissolves in acids, `Cr(OH)_(3)` is partially soluble while `Fe(OH)_(3)` is not soluble in aqueous `NH_(3)`. Only `Cr(OH)_(3)` not `Fe(OH)_(3)` is soluble by `NaOH//H_(2)O_(2)` according to the reaction.
