Question
What are emulsions? What are their different types? Give one example of each type.
Solution
Emulsions are the liquid−liquid colloidal systems, obtained on mixing two immiscible or partially miscible liquids.
There are two types of emulsions.
(1) Oil dispersed in the water type (O/W) : Here water is the dispersion medium, e.g. milk.
(2) Water dispersed in oil type (W/O) : Here oil is the dispersion medium, e.g. butter.
