N2  - The electrolytic conductance of solutions of potassium chloride and tetrabutyl- ammonium picrate over a range of concentrations have been measured in dioxan-water mixtures containing 0, 25, 50, 70, and 80% dioxan at 25º and pressures up to 1000 and 2500 bars respectively for the two solutes. The solvent concentration range corresponds to a range of dielectric constants of 78.3 (for water) to 11.98 (80% dioxan). The association of KCl in solutions of low dielectric constant is reduced by increasing pressure, so that the conductances of the solutions of finite concentration are not reduced as much by pressure as at infinite dilution. In contrast to this, the solutions of the tetrabutylammonium picrate are wholly dissociated even in very low dielectric constant solvents, as is shown by the limited concentration dependence of the conductance pressure characteristics.
