111. Solving a chemistry problem

53. Plot the ζ,-potential as a function of the pore diameter of a quartz diaphragm using the following experimental electroosmosis data:
Pore diameter, d*l06m 3.0 35.0 70 150
Volume velocity v*IO9 m3/s 0.12 0.24 0.34 0.37

Current strength I = 0.32*10-3 A, electrical conductivity χ = 1.6 Ohm-1*m-1, viscosity
dispersion medium η \u003d 10-3 N * s / m2, ε \u003d 81, ε 0 \u003d 8.85 * 10-12 F / m.
