Answer 1

Aim : 

To separate two miscible liquids (water and acetone) by distillation. 

Materials required : 

Stand, distillation flask, thermometer, condenser, beaker, acetone and water, one holed rubber cork.

Procedure: 

1.  Take a mixture of acetone and water in a distillation flask. 
2.  Fit it with a thermometer and clamp it to stand. 
3.  Attach the condenser of the flask on one side. 
4.  On the other side of the condenser keep a beaker to collect distillate.
5.  Heat the mixture slowly. 
6.  Keep a close watch on the thermometer. 
7.  The acetone vapourizes and condenses in the condenser. 
8.  The acetone can be collected from the condenser outlet. 
9.  Water remains in the distillation flask.
