How are colloid classified on the basis of: ltbtgt (a) physical state of components
(b) nature of dispersion medium
(c ) interaction between dispersed phase and dispersion medium ?

Explanation

(a) Based on physical states f components, Based on physical states of components i.e., dispersed phase and dispersion medium, there are eight types of colloidal soutions. For details, Consult Section 16.
(b) Nuture of dispersion medium. The dispersion medium can be ither gas, liwuid or solid. Based upon its nature, the colloids or colloidal solutions are of three types.
Aerosols : Air or gases act as the dispersion medium
Liquid sols : Liquids like water, alcohol or benzene act as the dispersion medium.
Solid sols : Solid acts as the dispersion medium. For details, consult section 16.
(c ) Interaction between dispersed phase and dispersion medium. Colloidal solutios are classified into two types. These are lyophilic and lyophobic sols. For details, consult Section 17.
