      Explain the cause of adsorption.

    Answer:

                                             Adsorption arises due to the fact that the surface particles of the adsorbent are not in the same environment as the particles inside the bulk. In side the adsorbent all the forces acting between the particles are mutually balanced  but on the surface the particles are not surrounded by atoms or molecules of their kind on all sides and hence they possess unbalanced or residual attractive forces. These forces are responsible for attracting the adsorb ate particles on its surface.
