%X Measurements have been made on several electrolytes of their apparent molar volumes at 25&#176;C by dilatometry and typically from 0&#176;C to 125&#176;C by expansimetry in propylene carbonate, N- methylformamide, formamide, and methanol. The electrolyte limiting apparent molar volumes are shown to be linearly related to the temperature dependent isothermal compressibility in these solvents, as in water. Ion-pair equilibrium associated constants have been determined by volumetric means for NH4SCN, KSCN and ten other electrolytes in acetonitrile at 25&#176;C and similarly for MgSO4 in water at 25&#176;C. Less extensive apparent molar volume studies in water 0 to 160&#176;C for high charge species and in liquid sulfur dioxide at 25&#176; are also reported.
