Not in JEE Main or NEET syllabus

Match column I (process) with column II (application)

Column I A) Dialysis B) Peptization C) Emulsification D) Electrophoresis

Column II a) Cleansing action of soap b) Coagulation c) Colloidal solution preparation d) Purification of colloidal solution

(A)A=d, B=a, C=c, D=b
(B)A=d, B=c, C=a, D=bCorrect
(C)A=c, B=b, C=d, D=a
(D)A=b, B=c, C=a, D=b

Answer: (B)

Solution

Dialysis separates dissolved ions and molecules from a colloid through a semipermeable membrane, so it is used for purification of a colloidal solution (A = d). Peptization converts a freshly precipitated substance into a colloidal sol with a small amount of electrolyte, so it is colloidal solution preparation (B =
