23. The hydrogen bubble moves to the anode at a speed of 8.4⋅10 ^ -6 m / s with an external field gradient of 100 V / m. Determine the electrokinetic potential at the hydrogen-water interface if the dielectric constant of water is ε = 81; temperature of the experiment T = 293 K; ε0 = 8.85⋅10 ^ -12 F / m.
