Filtration
________ can be used if your product is an insoluble solid that needs to be seperated from a liquid reaction mixture.
3
New cards
Insoluble
________ means the solid cant be dissolved in the liquid.
4
New cards
Crude oil
________ is a mixture of different length hydrocarbon molecules.
5
New cards
nitrogen
Air is a mixture of gases, mainly ________, oxygen, carbon dioxide and argon.
6
New cards
Evaporation
________ 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.
7
New cards
dry crystals
Evaporate the water from the salt so that it forms ________.
8
New cards
water evaporates
The ________ and is condenses and collected.
9
New cards
separate parts
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.
10
New cards
filter paper
The salt passes through the ________ as its part of the solution.
11
New cards
filtration
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.
12
New cards
Mixtures
are easily separated, as theres no chemical bonds
13
New cards
chromatography
a process used for separating mixtures by virtue of differences in absorbency
14
New cards
paper chromatography
chromatography that uses selective adsorption on a strip of paper
15
New cards
Simple distillation v fractional
fractional can separate multiple mixtures of liquids
16
New cards
crystallisation process
pour solution on evaporating dish, crystals will form and filter crystals out of solution
17
New cards
crystallisation
use if salt does decompose
18
New cards
Evaporation process
pour solution into dish, slowly heat it solvent will evaporate and crystals will form
19
New cards
Evaporation
letting liquid boiling away so crystals are left
20
New cards
What does filtration separate
insoluble solids from liquids
21
New cards
Filtration
the process whereby fluids pass through a filter or a filtering medium
22
New cards
simple distillation
boil liquids until one with lower boiling point evaporates, then goes through condenser
23
New cards
fractional distillation
boil liquids at lowest boiling temperature until it separate, then the next until there all seperated
