Which of the following is most effective in coagulating a ferric hydroxide sol ?

A

KCl

B

`KNO_(3)`

C

`K_(2)SO_(4)`

D

`K_(3)[Fe(CN)_(6)]`

Text Solution

Verified by Experts

The correct Answer is:
D
Due to highest negative charge in the anion `[Fe(CN)_(6)]^(3-)`, it is most effective in coagulating `Fe(OH)_(3)` solution.
