Emulsions are mixtures of liquids that are immiscible or simply put, do not mix together.Rather they form a boundary between themselves for instance,oil and water.
There are two types of emulsions:
(a) Oil in water(O/W)type: In this case, oil is the dispersed phase (DP)while water is the dispersion medium(DM). Examples include milk and vanishing cream
(b) Water in oil (W/O)type:In this case, water is the DP while oil is the DM.Examples include coldcream and butter.
Final Answer :
Thus, emulsions are a form of colloid , where two immiscible liquids are dissolved together.
