1. The sol was obtained as a result of the exchange reaction by pouring 12 ml of 0.008 M CoCl2 electrolyte solution and 8 ml of 0.006 M Na2SO4 electrolyte solution.
Calculate the value of the ξ-potential for a given sol if its electrophoresis proceeds at an external electric field strength of 300 V/m. The movement of particles in 18 min was 15 mm in a medium with a viscosity of 10-3 N•s/m2.
To which electrode does the sol particle move?
