Question

Differentiate between emulsions and micelles taking a suitable example of each.

Answer 1

Emulsions	Micelles
Emulsions are colloidal dispersions of two immiscible liquids where one liquid is dispersed in the other.	Micelles are spherical aggregates of surfactant molecules formed in aqueous solution above the critical micelle concentration (CMC).
Stability is due to an emulsifying agent that prevents separation of the liquids.	Micelles form spontaneously due to amphiphilic nature of surfactants, with hydrophobic tails inward and hydrophilic heads outward.
They exhibit two liquid phases: dispersed phase and dispersion medium.	Micelles have no separate phase; they are molecular aggregates within a single phase.
Example: Milk is an oil-in-water emulsion where fat droplets are dispersed in water.	Example: Soap micelles encapsulate oily dirt to help in cleaning.
