Separation techniques

Question 1

Filtration

Answer 1

Separates an insoluble substance from a liquid

Question 2

chromatography

Answer 2

separates the components of a mixture where each component moves through a median at a different rate

Question 3

Crystallisation

Answer 3

separating solid compounds from the solution in the form of crystals.

Question 4

distillation

Answer 4

Simple - separates two miscible liquids that have boiling points at least 25 apart

Fractional - separates and isolates one or more liquids from a mixture with components whose difference in boiling point is less than 25

Question 5

sublimation

Answer 5

separation of a solid-solid mixture where one of the components sublimes (converts from solid state to gaseous state without forming liquid) upon heating, leaving behind the other components that are non-sublimable.

Question 6

decantation

Answer 6

separating a liquid from a solid or other immiscible liquids

Question 7

evaporation

Answer 7

Separates a soluble substance from a liquid

Question 8

Separating funnel

Answer 8
