a First to all Distillation is a laboratory technique used for separating and purifying liquids itworks by exploiting the different boiling temperatures of liquids To separate two or more liquids by distillation you first heat them in a flask The more volatile liquid the liquid with the lower boiling point will typically evaporate first and the vapor will pass into a condensing column where it can revert into a liquid condense on the cool glass where it trickles into a collection flask Heating further will cause the less volatile liquids to evaporate and distill at higher temperatures The two main kinds of distillation are simple distillation and fractional distillation and both are used widely A simple distillation apparatus consists of a boiling flask roundbottom flask attached to an adapter holding a thermometer to determine the boiling temperature of the liquid The adapter connects to a condenser into which cold water is constantly passed through The condenser leads into a collection flask for the purified liquid See Answer
