ON THE INFLUENCE OF REPULSIVE FORCES UPON THE MOVEMENT OF IONS IN WATER - A SIMPLE-MODEL

The participation of repulsive forces in the movement of ions in water is discussed in a simple context, namely by recognizing that the inte raction, resulting from their electronic charge distributions, between ions and water molecules produces a repulsion between them, due to Pa uli's exclusion principle. This is a quantum mechanical effect which, to our knowledge, has not previously been taken into account in treatm ents of this phenomenon. We have included this repulsive interaction a s a Born-Mayer-type term in the equation for ionic conductance publish ed by Zwanzig some years ago. The corrected ionic conductance obtained in this way fits experimental data fairly well.
