4. Calculate the ζ-potential of the corundum diaphragm in sodium chloride solution and plot the dependence of ζ on the pore diameter of the diaphragm using the following data:
d*106,m v*108,m3/s Xs*102,Ohm-1*m-1
7 2.8 1.48
10 3.2 1.3
15 3.6 1.15
25 3.9 1.05
50 4.0 1.02
Xv=1.5*102 Ohm-1*m-1; I=2*10-2A; n=1*10-3 Pa*s; e=81.
