    Write the main reason for the stability of colloidal sols.


    There are two main reasons for the stability of colloidal sols:
    Solvation: Colloidal particles are covered by a sheath of liquid in which they are extensively solvated, thereby providing stability.

    Electrostatic stabilisation: Presence of equal and similar charges on the colloidal particles prevents coagulation of the colloidal sol.
