Chemistry Filtration And Crystalisation Flashcards
What is filtration used to separate ?
Filtration is used to separate insolvable solid from a liquid
What does insoluble solid mean ?
Insoluble solid means solid that is not dissolved in the liquid.
What equipment do we use for filtration?
For filtration we use :
. Flask
. Filter funnel
. Filter paper
What is crystallisation used for ?
Crystallisation is used for separating soluble solid from a liquid.
What do we do for crystallisation?
. First boil the liquid
. Then we leave it in a cool dry place overnight
. Which then gives you crystals.
What is distillation used for ?
Distillation is used for separating liquid from a solid, but still want the liquid.
What do we do for distillation?
Distillation :
. First we evaporate the liquid by heating it
. Then we condense the vapour by cooling it
What does fractional distillation used for?
Fractional distillation is used to separate two different liquid
What do we use chromatography for ?
We use paper chromatography to separate substance based on their different solubilities
What is the stationary phase
Stationary phase is a phase that does not move
What is a mobile phase
A mobile phase is a phase that does move
