How can you separate a mixture of two miscible liquids? Take one example. Or Distinguish among true solution, suspension and colloid in a tabular form under the following characteristics. (i) Type of mixture        (ii) Stability (iii) Filterability              (iv) Size of solute (v) Visibility of particles  

Answer:

Example To separate acetone and water from their mixture. Procedure (i) Take the mixture in a distillation flask. Fit it with a thermometer. (ii) Set the apparatus as shown in the figure given below. (iii) Heat the mixture slowly and note the reading of thermometer. (iv) The acetone vaporizes condenser in condenser an can be collected in the beaker. (v) Water is left behind in the distillation flask.  (2) OR Difference between true solutions, suspension and colloid

Characteristics	True solution	Suspension	Colloid
Type of mixture	Homogeneous	Heterogeneous	Heterogeneous but appears to be homogeneous.
Stability	Stable, particles do not settle down on keeping.	Not stable, particulars settle down filter paper.	Stable, particles do not settle down on keeping.
Filterability	Passes through filter paper.	Do not pass through filter paper.	Passes through filter paper.
Size of solute	Very small i.e., less thancm in diameter.	Quite large i.e., large than cm in diameter	Between cm and cm in diameter
Visibility of particles	Not visible even with a powerful microscope.	Visible even with naked eyes.	Visible with the help of a microscope
