The potential of cells with liquid junctions is affected by diffusion of ions in the junction region. From the laws of diffusion, concentration profiles and values of potentials have been calculated for several different junctions without the assumption of activity coefficients equal to 1. The results have been compared to existing experimental data, and the results of the calculations of others. The magnitude of the diffusion effect has been calculated also for cases where it is desirable that the effect be negligible, as with an electrode of the second kind.
