Question 1

filteration

Answer 1

used to separate an insoluble solid from a liquid you use a filter funnel and a filter paper and the water leaves through the paper and the solid is left

Question 2

crystallisation

Answer 2

used to separate a soluble solid from a liquid. you make the solid evaporate

Question 3

distillation

Answer 3

used to separate water from a solid and keep the water. you heat the solution which turns into a gas and the rises up through the gas tube and then the gas goes through the cold condenser and then when it passes through the condenser it condenses and turns into a liquid and pours out so at the end were left with the crystals of the solid in the beaker and the liquid.

Question 4

condensing

Answer 4

gases to liquid

Question 5

chromatography

Answer 5

you draw a horizontal line in pencil because the pencil wont dissolve in the solvent and then you put dots of the colours you want to test then you have the solvent move up the paper and carrying the colours if the colours separate the compound is a mixture and if it has not separated the compound is pure
