Emulsions

Milk is an example of emulsion. These are formed when both the dispersed phase and dispersion medium are liquids in a colloidal system. If a mixture of two immiscible or partially miscible. liquids is shaken, coarse dispersion of one liquid on the other is obtained, which is known as emulsion. They also show Brownian movement and Tyndall effect. They can be broken into their constituent liquids by freezing, heating and centrifuging etc.
