7. Calculate the value of the ξ-potential at the boundary of the aqueous solution of KCl-
a polystyrene membrane, if in the process of electroosmosis the space velocity
was equal to 15⋅10 -10 m3 / s; current intensity J = 7⋅10 -3 A; conductivity
the medium is ω = 9⋅10 -2 Ω -1 ⋅ m -1; viscosity of the medium η = 10 -3 Pa · s; ε 0 = 8.85⋅10 -12 F / m;
ε = 81.
