Question

What are miclells? How do they differ from ordianry cordinary colloidal particles? Give two examples of micelles-forming substances.

Answer 1

There are some substance which at low concentration behave as normal electrolyte but at higher concentrations exhibit colloidal behaviour due to the formation of aggergated particles. The aggerated particles thus formation of aggerated particles. The aggregated particles thus formed are called micelles.
The formation of micelles takes place only above a particular temperature called Kraft temperature and above a particular concentration (CMC). On dilution these colloids revert back to individual inos. Examples are soaps and sytheric detergents.
