There is a electrolytic cell which has H_{2}SO_{4} as solvent with two identical platinum plates.

Ionic mobility = drift velocity / electrical field strength (U=V/E)

If I only know the Electrical field strength, Ionic mobility of the SO_{4}^{2-} and drift velocity of H^{+} ,

Is there any relationship between the ionic mobility of the SO_{4}^{2-} and drift velocity of H^{+} to calculate the ionic mobility of the H^{+}?

Is there any relationship between the drift velocities of H^{+} and SO_{4}^{2-} or ionic mobilities of H^{+} and SO_{4}^{2-}

or can I write the equation as U_{SO42-} = V_{H+}/E
