Types of Colloids

A colloid may be defined as a substance in a peculiarly fine state of subdivision dispersed in another continuous medium giving rise to a large increase in surface area of the dispersed phase. It diffused slowly and passed through membranes very slowly and the system is not always transparent to light. Examples of this group were gum, glue etc.

Depending on the dispersion medium and disperse phase colloidal systems have been grouped into different types. The material body which is present in a state of fine discrete particles is called the disperse phase and the continuous medium in which the discrete particles are present is called the dispersion medium. It is the continuous medium, such as a gas, liquid, or solid, in which a disperse phase is distributed. Table lists some of these,
