128. Solving a chemistry problem

9.7. Calculate the rate of electroosmosis of a potassium chloride solution through a corundum diaphragm, if it is known that ξ, calculated from the rate of electrophoresis of corundum particles in the same solution without taking into account electrophoretic braking, is 50 • 10-3
B; E \u003d 2 • 102V / m; ε = 81; η= 1 • 10–3Pa • s; Xv = 2 • 10–2 Ohm–1*m–1, æ • a = 3; a = 1.1; I = 2 • 10–2 A.
