349. A colloidal solution was obtained as a result of an exchange reaction by mixing equal volumes of solutions of FeCl3 with a concentration of 0.01 mol/l and NaOH with a concentration of 0.005 mol/l. Write the formula of a micelle of a colloidal solution and a diagram of its structure. In which direction (towards the cathode or anode) will the pellet move? Determine which of the electrolytes K2SO4 or KCl will have a lower coagulation threshold?
