Filtration and crystallisation

What are physical separation techniques used for

To separate mixtures

What is filtration used for

Separate an insoluble solid from a liquid (s and l)

How to perform filtration

Set up a filter funnel with filter paper inside. Pour the mixture into the filter paper. The liquid will pass through the tiny pores in the filter paper but the solid will remain in the funnel

What is the filtrate

The liquid that passes through the filter paper

Define residue

The solid/substance that remains on the filter paper

What is crystallisation used for

Separate a soluble solid from a liquid (aq and l)

How to do crystallisation

Leave the mixture, waiting for the liquid to evaporate, leaving crystals of the soluble solid behind. To quicken the process heat the solution go evaporation occurs quicker

What does aq mean

Aqueous solution (dissolved in water)
