Abstract

Electrolyte solutions with novel characteristics are formed by dissolution of ether in + hydrochloric acid solutions of high concentration. At 0°C ether is only slightly soluble in the "solution" , but dissolves in the solution until . Its solubility increases markedly in mixtures of these solutions, reaching a maximum near the mole ratio corresponding to the formation of , when . Furthermore, the solubility in this mixture increases with decreasing temperature, down to the glass transition temperature at −124°C. Although ionic mobilities appear to increase with increasing ether content the electrical conductance at 0°C decreases, evidently due to the disruption of an efficient proton transfer mechanism in the chlorozincate acid. The strongly proton conducting solutions may have useful low temperature electrolyte applications, since the conductivity is not necessarily limited by the ionic and molecular transport mechanisms which determine the fluidity.
