Solution
The correct option is C Electrodialysis
(A) Peptization:- It is a process used to stabilize a colloidal dispersion with the addition of a small amount of an electrolyte. The electrolyte used in the process is called a peptizing agent.
(B) Electrodialysis:- It is a process used for purification in which the dialysis is carried out under the influence of electric fields, to increase the process of purification.
(C) Coagulation:- In this process, the colloidal particles is settled down i.e., conversion of a colloid into a precipitate is called coagulation.
(D) Adsorption:- The phenomenon of accumulation of a substance in molecular species in higher concentrations on the surface is a adsorption.
Hence, electro-dialysis is used for purification of colloidal solution
