Methods used for the preparation of colloidal solutions are:
Methods used for the preparation of colloidal solutions are:
Open in App
Solution
The correct options are
A peptization
B ultrasonic dispersion
D hydrolysis
A process of converting a precipitate into colloidal sol called Peptization by shaking it with the dispersion medium.
Colloidal solutions of the hydroxides of Fe, Cr, Al etc can be prepared by hydrolysis of their salts
In ultrasonic dispersion, ultrasonic waves are passed through the solution containing larger particles. They break down to form the colloidal solution.
The process of settling of colloidal particles is called coagulation
