Immiscible

Definition

Immiscible describes liquids that do not mix together to form a homogeneous solution. When combined, immiscible liquids separate into distinct layers.

5 Must Know Facts For Your Next Test

1. Immiscible liquids have different polarities, which prevents them from mixing.
2. An example of immiscible liquids is oil and water.
3. The separation of immiscible liquids can be observed as distinct layers based on density.
4. Temperature changes generally do not affect the miscibility of immiscible liquids significantly.
5. In industry, separating immiscible liquids is often done using decantation or centrifugation.
