NOVEL ELECTROLYTE SYSTEM: SOLUTIONS OF DIETHYL ETHER IN CONCENTRATED AQUEOUS HCl plus ZnCl₂ MIXTURES.

The solubility in this mixture increases with decreasing temperature, down to the glass transition temperature at minus 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.
