Ion Velocity. In electrochemistry, the ion velocity is the speed at which ions move through the electrolyte between the electrodes. The ion velocity will be different for different ions. Since the total charge is constant (it is the equivalent conductance) then the equivalent conductance at infinite dilution can only depend on the speeds of the ions. If (u) and (v) are the velocities of the cation and anion respectively under a potential gradient of 1 volt per cm, then,  where  (δ) is the same constant for all electrolytes. Consequently, .
