Chapter 2: Separation Techniques

________ is used for separating out a liquid from a solution.

________ can be used if your product is an insoluble solid that needs to be seperated from a liquid reaction mixture.

________ means the solid cant be dissolved in the liquid.

________ is a mixture of different length hydrocarbon molecules.

Air is a mixture of gases, mainly ________, oxygen, carbon dioxide and argon.

________ is a really quick way of separating a soluble salt from a solution, but you can only use it if the salt doesnt decompose (break down) when its heated.

Evaporate the water from the salt so that it forms ________.

The ________ and is condenses and collected.

The properties of a mixture are just a mixture of the properties of the ________- the chemical properties of a substance arent affected by it being part of a mixture.

The salt passes through the ________ as its part of the solution.

The parts of a a mixture can be either elements or compounds, and they can be separated out by physical methods such as ________, crystallisation, simple distillation, fractional distillation and chromatography.

are easily separated, as theres no chemical bonds

a process used for separating mixtures by virtue of differences in absorbency

chromatography that uses selective adsorption on a strip of paper

fractional can separate multiple mixtures of liquids

pour solution on evaporating dish, crystals will form and filter crystals out of solution

use if salt does decompose

pour solution into dish, slowly heat it solvent will evaporate and crystals will form

letting liquid boiling away so crystals are left

insoluble solids from liquids

the process whereby fluids pass through a filter or a filtering medium

boil liquids until one with lower boiling point evaporates, then goes through condenser

boil liquids at lowest boiling temperature until it separate, then the next until there all seperated
