Question

How do micelles differ from normal colloidal solutions?

Answer 1

Point	Micelles	Normal Colloidal Solutions
Formation	Micelles are formed by the association of molecules (e.g. soap or detergent) above a certain concentration called the critical micelle concentration (CMC).	Normal colloidal solutions are formed by the dispersion of large molecules or aggregates in a dispersion medium.
Existence	Micelles exist only above the critical micelle concentration (CMC).	Normal colloidal solutions exist at all concentrations once formed.
Nature of Particles	Micelles contain both hydrophilic and hydrophobic parts, and are therefore amphiphilic in nature.	Particles in normal colloidal solutions may or may not be amphiphilic.
Example	An example of micelles is soap or detergent in water.	Examples of normal colloidal solutions include starch sol, gold sol, and sulphur sol.
