Resumen:
Theoretical aspects concerning the calculation of the distribution potential at the interface between two
immiscible electrolyte solutions are examined. In particular, we analyze the effect of the ratio between
the volumes of each phase (r) on the distribution potential for several systems with different levels of
complexity. First, we examine the effect of water autoprotolysis for a system composed of completely dissociated
electrolytes and weak bases. Finally, the effect of including the ion-pair formation on the potential
distribution is considered. In all cases, the algebraic expressions for the equilibrium distribution
potential, at r?0 and at r?1, are developed. The results presented in this work are of fundamental
importance for gaining further understanding of the basic properties of the partition of weak bases, with
direct application in drug partitions, and in the theoretical treatments of ion-selective electrodes and of
liquid extraction.
