The selective permeability of two species of critical ions coexisting in Solution 1 for a third species of ions of the same charge in Solution 2 penetrate through the anion exchange membrane has been studied. The competitive permeability of coexisting ions depends on various concentrations, compositions and reaction time with the restriction that the volume of solution in each compartment is finite. The species which is easy to exchange across the membrane in multi‐ionic system has a high selective permeability at small composition and high total concentration condition. The experimental result shows that there exist overshooting and depletion effects for the fast ion when the reaction time is long enough, and the higher the permselectivity T CL OH is, the more appreciable the overshooting effect is. An explanation of the overshooting and depletion effects with finite volume of solution has been made specifically in discussion.
