5. Write the formula for a particle of the dispersed phase of the sol obtained as a result of an exchange reaction by pouring 10 ml of a 0.008 M CoCl2 electrolyte solution and 7 ml of a 0.005 M NaOH electrolyte solution.
Calculate the value of the ξ-potential for a given sol if its electrophoresis occurs at an external electric field strength of 500 V/m. The movement of particles in 10 minutes was 12 mm in a medium with a viscosity of 10-3 N∙s/m2. To which electrode does the sol granule move?
