Subjective Type

What are emulsions? What are their different types? Give examples of each type.

Solution

Emulsions are colloidal solutions with both dispersed phase and dispersion medium being liquid. Thus, finely divided droplets of one liquid are dispersed in another medium. Emulsions can be formed from any two immiscible liquids.

Two types of emulsions include oil in water emulsion and water in oil emulsion.

Oil in water emulsion :
The dispersed phase is oil. It is present in a small amount. The dispersion medium is water. It is present in a large amount.
For example, milk is an emulsion of soluble fats in water.

Water in oil emulsion :
The dispersed phase is water. It is present in a small amount. The dispersion medium is oil. It is present in large amount.
For example, butter is an emulsion of water in oil.
