10) Using the experimental data of electroosmosis, show graphically how the value of the electrokinetic potential on the quartz membrane changes with increasing concentration of the KCl solution:

KCl concentration (kmol/m3) 1*10-4 1*10-3 1*10-2 1*10-1

Electrical conductivity, Ohm-1*m-1 1.5 *10-3 1.25 *10-2 1.22 *10-1 1.05

Volumetric velocity, m3/s 25*10-8 17.5*10-8 14.0 *10-8 4.5 *10-8

Current, A 2*10-5 4*10-4 7*10-3 2*10-2

Relative permittivity ε=81, electrical constant ε0= 8.85 *10-12 F/m, medium viscosity η= 10-3 H*s/m2
