Question

Mention the properties of colloidal solutions.

Answer 1

Colloidal Solution:- It is a heterogeneous mixture made up of two phases namely, dispersed phase and dispersion medium.

The properties of colloidal solutions are:-

1. A colloid is a heterogeneous mixture.
2. The size of particles in a colloid ranges between 1nm and 100 nm in diameter which is bigger than those in a true solution but smaller than those in a suspension.
3. The size of particles is too small to be individually seen by naked eyes. They cannot be seen even with the microscope.
4. Particle of colloids show brownian motion.
5. The particles of colloid are big enough to scatter a beam of light passing through it and thus, make its path visible (Tyndall effect).
