B.	Soap mixed with water above critical micelle concentration.	2. Molecular colloids
C.	White of egg whipped with water.	3. Associated colloid
P	With water below critical	4. Macromolecular colloids

         

Answer:

                        A. ® (2)    B. ® (3)    C. ® (4)   D. ® (1) A. When sulphur vapours passed through cold water it leads to formation of molecular colloids. B. When soap is mixed with water above critical micelle concentration it lead to formation of associated colloids. C. White of egg whipped with water is an example of macromolecular colloids in which high molecular mass proteneous molecule acts as a colloidal particle. D. Soap mixed with water below critical micelle concentration is known as normal electrolyte solution.
