One of the following solutions must be added to 5 cm3 of iron (III) hydroxide sol to start explicit coagulation: 4 cm3 of 3N potassium chloride solution; 0.5 cm3 0.01 n solution of potassium sulfate, 3.9 cm3 0.0005 n solution of potassium ferricyanide. Calculate the coagulation threshold for these electrolytes. How many times is the coagulating ability of K4[Fe(CN)6] higher than that of K2SO4 and KCl?
