A Colloid is a heterogeneous mixture of two components, one microscopically dispersed into another substance.

It consists of two parts a) Colloidal particle b) Dispersion medium.

Colloidal particle is a solute having its size range between 1 nanometer to 1 micrometer , i.e  1 * 10^-9 m  to 1 * 10^ -6 m

Types of Colloids are:

  1. Sol : A solid in liquid medium
  2. Emulsion: A Liquid in liquid medium
  3. Foam: A Gas in liquid medium.
  4. Aerosol: Solid / Liquid in gaseous medium.

Some of the Applications of Colloids:

  • Purification of water : Colloidal particles in the water are purified by different electrolysis methods.
  • Cleansing : Generally the soap action involves colloidal behaviour.
  • Medicinal field : Our body tissues absorb these small colloidal particles more easier, so medicines are made by colloids.
