Aluminium hydroxide forms a positively charged sol.
Which of the following ionic substances should be most effective in coagulating the sol?

A

`NaCl`

B

`CaCl_(2)`

C

`Fe_(2)(SO_(4))_(3)`

D

`K_(3)PO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Al(OH)_(3)` is positively charged sol. `K_(3)PO_(4)` has greater negative charge. Hence, it is most effective in coagulation of `AlOH)_(3)` sol.
