1. The light will be scattered by starch solution present in beaker B.
2. The Brownian movement will be observed in beaker B.
3. The name of the solution present in the beaker B is ‘true solution’ and that of solution present in beaker B is ‘colloidal solution.
4. The solution in beaker A which is solution of sugar mixed with water is homogeneous solution.
5. The particles of size 10A and 2000A are in beaker B.
