Impedance spectra are reported for PVC based membranes containing KBPh, + valinomycin in contact with aqueous solutions of (a) 1O-2 M KCI, (b) lo-' M LiCl and (c) lo-' M NaCl. In the KCl case there is evidence for the rapid exchange of K\* between the membrane phase and the aqueous solution. For LiC
