video about fractional distillation

fractionating column


the fractioning columns help to separate the mixture by allowing the mixed vapors to cool, condense, and vaporize again.

fractional distillation


this technique enables one to separate a miscible liquid to form a solution.

the condenser and the boiling chip




CONDENSER
Its function is to condense the hot vapour to water.the condenser is always slanted to ensure the liquid is flowing down, the water enters at the bottom so that the water will fill up the whole condenser.


BOILING CHIPS
Its function is to ensure smooth boiling and to prevent too much bubbling.
