Calculate the mass of the sediment formed on the electrode during electrophoresis of an aqueous suspension of corundum at an electric field strength of 1 * 102; 2 * 102; 4 * 102 V / m; suspension concentration c = 2.0 * 103 kg / m3. The duration of the deposition is t = 10 s, the e-potential, determined from the speed of electroosmosis without taking into account the surface conductivity, is 49.6 * 10-3 V, the coefficient of the diaphragm fusion is 1.8, e = 81, the surface of the flat electrode S = 1 * 10 -4 m2-; n = 1 * 10-3 Pa * s.
