Distinguish between true solution and colloidal solution.

The size of colloidal particles ranges between:

Which of these statements is/are true?

In which of the following does scattering of light takes place?

Give one example for each of the following types of mixtures
(a) solid-solid homogeneous mixture
(b) heterogenous mixture
(c) mislane liquids
(d) liquid-gas homogeneous mixture 

Assertion :Colloidal sols scatter light while true solutions do not.
Reason :The particles in the colloidal sol move slower than that of the true solutions.

Assertion :The values of colligative properties are of smaller order as compared to values shown by true solutions at same concentrations.
Reason :Colloidal particles show Brownian movement.

The size of particles in suspension, true the solution and colloidal solution varies in the order

Differentiate true solution and colloidal solution.
