Multiple Liquid Phases: Miscibility

Oil and vinegar are almost perfectly immiscible

A system can have multiple liquid phases when the substances do not dissolve in each other. Such substances are called immiscible.

For example, oil is not miscible in water. Thus, when oil and water are mixed, two layers, or liquid phases, will exist.

When a system has multiple liquid components that completely dissolve in each other, they are said to be miscible.

The resulting mixture can be considered a pure substance if neither liquid participates in a chemical reaction.
