Answers (1)
Classification of colloids based on type of particles of the dispersed phase:
- Multimolecular colloids
- Macromolecular colloids
- Associated colloids
Macromolecular colloids
Macromolecules in suitable solvents form solutions in which the size of the macromolecules may be in the colloidal range.
Stability: These colloids are quite stable and resemble true solutions in many respects.
Examples include starch, cellulose, proteins, enzymes, polythene, nylon, polystyrene, synthetic rubber, etc.
Hence option 3 is correct.
