Abstract

The conductance of s-acetylthiocholine halides and perchlorate has been measured in ethanol – water mixtures (28.6 < D < 72.0).  The conductance parameters derived from Fuoss – Onsager conductance theory indicate that the solvation of halides and perchlorate decreases with the decrease of the dielectric constants until a certain minimum and then increases again. The plot of log kA vs. 1/D is found to be non linear indicating that the equation of association cannot be applied. The association constant is analyzed using the solvent separated – ion pair model.
