Potential drop across the mobile part of the double layer, that is responsible for electrokinetic phenomena. $$\zeta$$ is positive if the potential increases from the bulk of the liquid phase towards the @[email protected] In calculating the electrokinetic potential from electrokinetic phenomena it is often asumed that the liquid adhering to the solid wall and the mobile liquid are separated by a sharp shear plane. As long as there is no reliable information on the values of the @[email protected] and the @[email protected] in the electrical double layer close to the @[email protected], the calculation of the electrokinetic potential from electrokinetic experiments remains open to criticism. It is therefore essential to indicate in all cases which equations have been used in the calculation of $$\zeta$$. It can be shown, however, that for the same assumptions about the @[email protected] and @[email protected] all electrokinetic phenomena must give the same value for the electrokinetic potential.
