Method of formation of solution is given in Column I. Match it with the type of solution given in Column II.
Column I Column II
(i) Sulphur vapours passed through cold water (p) Normal electrolyte solution
(ii) Soap mixed with water above critical micelle concentration (q) Multi molecular colloids
critical micelle concentration
(iii) White of egg whipped with water (r) Associated colloid
(iv) Soap mixed with water below (s) Macro molecular colloids
critical micelle concentration

Options:

A . i-q, ii-r, iii-s, iv-p

B . i-p, ii-q, iii-r, iv-s

C . i-q, ii-p, iii-s, iv-r

D . i-r, ii-s, iii-q, iv-p

Answer: Option A
:
A

Sulphur sol consists of particles containing a thousand or more of $S_{8}$ molecules => Multi molecular colloids

Below CMC, soap with water behaves as a normal electrolyte and above CMC as associated colloid
