ICSE Class 7 Answered
PRINCIPLE: This method is used for the separation of components of a mixture containing two miscible liquids that boil without decomposition and have a sufficient difference in their boiling points.
TECHNIQUE: Take the mixture in a distillation flask. Fit the thermometer. Arrange the apparatus as shown in the given figure.
Heat the mixture slowly, keeping a close watch on the thermometer.
The liquid with a low boiling point will vaporise and condense in the condenser and can be collected from the condenser outlet.
The liquid with higher boiling point will be left behind in the distillation flask.
