| (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) | Macro-molecular colloids |
Answers (1)
(i - b), (ii-c), (iii-d), (iv-a)
(i) Molecular colloids are formed when sulphur vapour is passed through cold water.
(ii) Associated colloids are formed when soap is mixed with water and the concentration exceeds critical micelle concentration.
(iii)Macro-molecular colloids are formed when the white of egg is whipped with water.
(iv) Normal electrolyte solution is formed when soap is mixed with water and the concentration is below the critical micelle concentration.
