Flashcards on Mixtures and Seperation Techniques

Decantation

A technique where you carefully pour the liquid off the top of a solid–liquid mixture or a liquid–liquid mixture, to separate the two components.

Flocculant

A chemical that helps with decanting, causes suspended particles to clump together so that they sink (forming sediment) and can be separated from the liquid they were suspended in by decantation.

Flotation

Separating a mixture based on the capacity to float.

Filtration

Separating a mixture by passing through a filter.

Filtrate

The substance that passes through the filter.

Residue

The substance that is left in the filter.

Centrifuge

A device that uses speed to separate substances based on mass.

Chromatography

A technique to separate substances based on movement at different rates due to solubility.

Evaporation

When liquid changes to a gaseous state.

Crystallisation

Solidification of a substance into a highly structured form.

Distillation

A technique to separate substances in a liquid using evaporation (boiling) and condensation.

Distillate

The condensed liquid product from distillation
