Q5 of 31 Page 1

Write the reason for the stability of colloidal sols.

1. The stability of a colloidal solution is due to fact that the colloidal particles in the sol are electrically charged.


2. The particles, therefore, repel on another and do not come close together to form large non-colloidal particles.


3. The Brownian Movement is also responsible for the stability of the colloidal sol.


4. Brownian movement opposes the force of gravity and does not allow the colloidal particles to settle down.
