8.19. Using experimental data, verify the theory of rapid coagulation of a gold hydrosol with an initial concentration of v0 = 5.22 * 10 ^ 14 ppm / m3 under the action of sodium chloride at a temperature of 291 K, viscosity
dispersion medium n = 1.06 * 10–3 Pa * s. Determine the half coagulation time and coagulation constant.
t, s 0 60 120 300 600 900
