Lesson 3.1 - Separation Techniques

Where the particles are being separated by size.

Sieving

Where the solid particle is being separated from a liquid or a gas using a — medium.

Filtration

Where you would separate mixtures in terms of their density.

Sedimentation

Usually after sedimentation. Involves pouring off a liquid from above the insoluble particles that have settled at the bottom.

Decantation

The ability of a liquid solute to dissolve in a liquid solvent & can form a homogeneous mixture.

Miscibility

The inability of a liquid solute to dissolve in a liquid solvent, creating 2 distinct layers ( heterogeneous mixture ) .

Immiscibility

Involves rapidly spinning a mixture of substances that have different densities.

Centrifugation

A piece of laboratory glassware that is commonly used to separate 2 immiscible liquids with different densities.
