Describe and explain the theories of emulsification
Answers
Two immiscible liquids, not yet emulsified
An emulsion of Phase II dispersed in Phase I
The unstable emulsion progressively separates
The surfactant (outline around particles) positions itself on the interfaces between Phase II and Phase I, stabilizing the emulsion
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, and some cutting fluids for metal working.
