Thermodynamic Properties of Aqueous Electrolyte Solutions. Compressibility Studies in 0.1, 0.5 and 1.0 mol⋅kg−1 Lithium Chloride Solutions at Temperatures from 278.15 to 323.15 K

Sound velocities in aqueous 0.1, 0.5 and 1.0 mol⋅kg−1 lithium chloride solutions were determined at 1 K temperature intervals from 278.15 to 323.15 K. These velocities served to evaluate the isentropic compressibilities κS, the isothermal compressibilities κT, the apparent molar compressibilities K2,φ, the isochoric thermal pressure coefficients (∂P/∂T)V, the change of cubic expansion coefficients with pressure at constant temperature (∂α/∂P)T, and the changes of heat capacities CV with volume (∂CV/∂V)T and CP with pressure (∂CP/∂P)T.
