Dialysis is a process used for
Aremoving dissolved ions and small molecules from a sol using a semipermeable membrane
Bconverting a lyophobic sol into a lyophilic sol
Ccoagulating a sol by heating
Dmeasuring the charge on colloidal particles
Answer: A
In dialysis the sol is placed in a bag of semipermeable membrane. Ions and small molecules diffuse out through the membrane into water, while the large colloidal particles stay inside. It is thus a method of purification of a sol.
