Calculate the volume of the solution transferred through the corundum membrane in 1 h as a result of electroosmosis of a weak electrolyte solution under the action of emf. 100 V. The electrokinetic potential of the corundum surface is 0.08 V. The relative dielectric constant of the medium is 80.1, the viscosity is 1 * 10-3 Pa * s, the electrical resistance of the membrane with this solution is R1 = 3900 Ohm.
To determine the electrical conductivity of the solution, including a correction for surface conductivity, the electrical resistance of the membrane was measured at 0.1 N. KCl solution, which turned out to be equal to R2 = 41.0 Ohm. Specific electrical conductivity 0.1 N. KCl solution is 1.167 Sm*m-1. Calculate the energy consumption required to transfer 1 m3 of solution.
