    () Nature of dispersion medium and
    () Interaction between dispersed phase and dispersion medium?
    Ans : On the basis of the physical state of the components (by components we mean the dispersed phase and dispersion medium). Depending on whether the components are solids, liquids, or gases, we can have eight types of colloids.
    () On the basis of the dispersion medium, sols can be divided as:









    Dispersion medium
    		 Name of sol
    Water
    		 Aquasol or hydrosol
    Alcohol
    		 Alcosol
    Benzene
    		 Benzosol
    Gases
    		 Aerosol


    () On the basis of the nature of the interaction between the dispersed phase and dispersion medium, the colloids can be classified as lyophilic (solvent attracting) and lyophobic (solvent repelling).
    () On the basis of the dispersion medium, sols can be divided as:
