Question
Which substance forms the emulsion from the following?
- Foam
- Ice-cream
- Face creams
- Cheese
Hint:
Ice-cream
The correct answer is: Ice-cream
- An emulsion is considered as a type of colloid created by combining two typically incompatible liquids. One liquid has a dispersion of the other liquid in an emulsion. Emulsions are commonly found in egg yolks, butter, and mayonnaise. The process to combine liquids to form an emulsion is known as emulsification.
- Ice cream, which is a mixture of two liquids that do not ordinarily combine, is an emulsion. Here, one of the liquids is mixed with the other. Ice cream contains liquid fat particles called fat globules that are distributed throughout a mixture of water, sugar, and ice, as well as air bubbles.
