Distillation Flashcards
The steps of simple distillation are :
A solution is heated, usually using a Bunsen burner.
The liquid in the mixture evaporates into a gas.
The gas is cooled by a water jacket, and condenses into a liquid, which then flows into the beaker.
Fractional distillation can separate a mixture of several liquids that each have different:
Boiling points
Briefly explain the process of fractional distillation to separate a mixture of the liquids methanol, ethanol and propanol.
Heat is applied and the liquid with the lowest boiling point evaporates and condenses into a beaker.
If other liquids evaporate by chance, they condense in the fractionating column back into the flask.
The temperature is altered to repeat the process for the second liquid.
The three liquids are separated based on differing boiling points with the third remaining in the flask.
