1. explain the process of distilling water with a neat labelled diagram? plz fast
Answers
Activity :
• Take the mixture in a distillation flask. Fit it with a thermometer.
• Arrange the apparatus as shown in figure.
• Heat the mixture slowly keeping a close watch at the thermometer.
• The acetone vapourizes, condenses in the condenser and can be collected from the condenser outlet
• Water is left behind in the distillation flask.
Criterion : Two miscible liquids that boil without decomposition and have sufficient difference in their boiling points can be separated by this method.
Explanation:
Answer :
The boiling point of alcohol is 78°C and boiling point of water is 100°C therefore a mixture of alcohol and water can be separated by fractional distillation. The alcohol with boiling point 78°C will distil first and then water with boiling point 100°C will distil later. Fractional distillation separates the various liquids according to their boiling point, the more volatile liquid (having lower boiling point) distils first and the less volatile liquid (having higher boiling point) distils later.
