Description
How is a homogeneous mixture different from a heterogeneous mixture?
Most materials in our surroundings are mixtures of two or more components. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are uniform in composition, but heterogeneous mixtures are not uniform in composition.
Air is a homogeneous mixture, and oil in water is a heterogeneous mixture. Homogeneous and heterogeneous mixtures can be separated into their components by several physical methods. The choice of separation techniques is based on the type of mixture and the difference in the chemical properties of the constituents of a mixture.
Types of separation processes:
- Crystallization
- Filtration
- Decantation
- Sublimation
- Evaporation
- Distillation
- Chromatograph
- Centrifugation
- Separating funnel
- Magnetic separation
- Precipitation
Using a separating funnel:
A separating funnel is used for the separation of components of a mixture between two immiscible liquid phases. One phase is the aqueous phase, and the other phase is an organic solvent. This separation is based on the differences in the densities of the liquids. The liquid having more density forms the lower layer, and the liquid having less density forms the upper layer.
Applications:
- To separate a mixture of oil and water.
- To separate a mixture of kerosene oil and water.
