Interpretation: Things that make the stability of a colloidal dispersion need to be explained.
Concept Introduction: A colloidal dispersion is made up of solid, liquid, or gas particles in a dispersed phase. Colloidal particles range in size from 1 nm to
Explanation of Solution
There are two ways by which a colloidal dispersion can be stabilized.
- By adding a coat of
polymer on the surface of colloidal dispersion. - By increasing the charge on the surface
The method by which the coating of polymer is done on the surface is known as steric stabilization. On the other hand, increasing in charge is known as electrostatic stabilization. Both methods can also be combined to stabilize the colloidal dispersion.
Therefore, two methods are steric stabilization and electrostatic stabilization.
