Match Column I with Column II
| Column I | Column II |
| i. Sulphur vapours passed through cold water | a. Normal electrolyte solution |
| ii. Soap mixed with water above critical micelle concentration | b. Molecular colloids |
| iii. White of egg whipped with water | c. Associated colloid |
| iv. Soap mixed with water below critical micelle concentration | d. Macromolecular colloids |
Answer & explanation
Correct answer: option 2
(i) By passing vapours of Sulphur through cold water sulphur sol can be prepared which is a molecular colloid.
(ii) When soap is mixed with water above critical micelle concentration forms associated with colloid.
(iii) White of egg whipped with water forms a macromolecular colloid.
(iv) Soap mixed with water below critical micelle concentration behave as the normal electrolyte.
