45. Based on the electrophoresis velocity, calculate the electrokinetic potential of the sol obtained by chemical condensation according to the corresponding reaction (see Table 1). The permittivity of water is 81, the electric constant is 8.85 • 10-12 F/m. The viscosity of water is 10-3 Pa•s. The electric field strength and electrophoresis velocity are given in Table 2. Provide the structure of the sol micelle and indicate to which electrode the sol particles move during electrophoresis.
