`Fe(OH)_(3)` can be separated from `Al(OH)_(3)` by the addition of

A

NaCl solution

B

Dil. HCl solution

C

NaOH solution

D

`NH_(4)Cl and NH_(4)OH`

Text Solution

Verified by Experts

The correct Answer is:
D
Due to common ion effect of `NH_(4)^(+)` , concentration of `OH^(-)` decreases , as `K_(sp)Fe(OH)_(3) lt K_(sp)Al(OH)_(3)` thus `Fe(OH)_(3)` get precipitated first .
