Filtration And Crystallisation Flashcards
What are physical separation techniques ?
They are techniques that superset mixtures but cannot separate a compound
What is filtration used for ?
Separate an insoluble solid from a liquid
Insoluble means the solid does not dissolve in the liquid
What apparatus do we use when doing filtration?
Conical flak with a filter funnel and filter paper
How would we carry out filtration ?
First get a conical flask and put a filter funnel with filter paper on the top
Then pour the mixture into the filter paper
The solid cannot pass through and once all the filtrate is separated we have fully spederated the mixture
What is the liquid that passes through the filter paper called ?
The filtrate
What is crystallization used for ?
Separate a soluble solid from a liquid
This is another physical seperation method
How do we carry out crystallization ?
You get the mixture and place it in a beaker and gently heat the solution which speeds up the reaction to evaporate the water
After some time has passed crystals will from once the water has evaporated
