Distillation Flashcards
What is distillation used for?
To separate liquids from mixtures.
What equipment is needed for distillation?
A condenser, a flask, a beaker and a way of heating it.
What is fractional distillation used for?
A liquid from a mixture of liquids.
Why does simple distillation work?
The solute (solid) has a higher boiling point than the solvent (liquid). When the solution is heated the solvent boils and vapor passes into the condenser. The vapor is cooled down and condenses back to the liquid state, leaving the solute behind. The solution also becomes more concentrated.
Why does fractional distillation work?
Because the liquids in the mixture have different boiling points.
What is the function of the condenser?
To cool the liquid vapor down as it passes through and change it back to a liquid state.
