FAQs on Multimolecular, Macromolecular & Associated Colloids Video Lecture - Chemistry Class 12 - NEET

1. What is the difference between multimolecular, macromolecular, and associated colloids?
Ans. Multimolecular colloids are formed by the aggregation of small molecules or ions, while macromolecular colloids consist of large molecules, such as polymers or proteins. On the other hand, associated colloids are formed by the association of smaller molecules that can form aggregates or micelles in certain conditions.
2. What are some examples of multimolecular colloids?
Ans. Some examples of multimolecular colloids include gold sols, silver sols, and sols formed by small organic molecules like dyes.
3. Can you provide examples of macromolecular colloids?
Ans. Yes, examples of macromolecular colloids include gelatin, starch, cellulose, and proteins like albumin or collagen.
4. How do associated colloids form?
Ans. Associated colloids form when certain molecules, called surfactants, self-associate in solution to form micelles or other aggregated structures. This can occur when the concentration of surfactant exceeds a critical micelle concentration (CMC).
5. What are the applications of these types of colloids?
Ans. Multimolecular colloids find applications in industries like electronics, catalysis, and medicine. Macromolecular colloids are used in food industry, pharmaceuticals, and cosmetics. Associated colloids have applications in detergents, emulsions, and drug delivery systems.
