What are micelles? How do they differ from ordinary colloid particles? Give two example of micelles forming substances.

Answer:

Micells. Those substances which when dissolved in a medium at low concentrations behave like electrolytes but in high concentration it shows colloidal state due to formation of aggregated particles
The formation of micelles takes place only above particular temperture ca;;ed kraft temperture and above a particular concentration called critical micellesation concentration (CMC). On dilution these colloids revert back to individual ion.
e.g., soaps and detergents form micells.
