Filtration + crystallization + Distillation

Question 1

When can filtration be used to serpate a mixtufre

Answer 1

Can be used when you have a mixture of an insoluble solid from a liquid

Question 2

When can crystalisation be used to seperate a mixture

Answer 2

Can be used to separate a soluble solid from a solution

Question 3

Explain how filtration works

Answer 3

Passing the Mixture through a filter and seperating solids from the liquid

Question 4

Why might crystalisation be used instead of evaporation

Answer 4

Used if the salt will decompose when heated

Question 5

What equipmeant would you need to carry out crstalisation

Answer 5

Evaporating dish, heat source, beaker, flask, funnel and filter paper

Question 6

Explain how filtration and crystallization can be used to separate a mixture of sand and salt

Answer 6

Filtered to remove sand and heated up to isolate the salt

Question 7

What sort of mixture can fractional distilation be used to seperate

Answer 7

Mixtures of similar boiling point liquids

Question 8

Explain why simple distillation cant be used to separate substances with similar boiling points

Answer 8

They would evaporate and mix together at the same time
