2. Calculate the values of the electrokinetic potential ζ and plot the dependence of ζ on the concentration of potassium chloride c from the following data obtained from studying the electroosmosis of an aqueous KCl solution through a porous corundum diaphragm:
s, mmol/l κ*102, Ohm-1*cm-1 (V/t)*109, m3/s
0.2 0.324 0.750
0.4 0.610 0.500
0.9 1.322 0.250
1.4 2.033 0.125
2.0 2.885 0.05

Relative dielectric constant 80.16, viscosity 1.00 mPa*s; current strength 1.5*10-3A.
