Description

13. Calculate the value of the ξ-potential at the boundary of the collodion membrane-an aqueous solution of KCl, if, upon extrusion of this solution through
membrane under pressure 25,5⋅10 3 Pa flow potential Ε теч = 8,8⋅10 -3 V; ε = 81; ε 0 = 8.85⋅10 -12 F / m; viscosity of the medium η = 10 -3 Pa · s; the specific electrical conductivity of the medium is ω = 1.5⋅10 -2 Ω -1 ⋅ m -1.
