Abstract: Thermodynamic properties like partial molar volume(ϕv0), B-Coefficients and partial molar compressibility (ϕk0) of aqueous lithium chloride solutions has been determined at 30, 35, 40, 45 and 50oC in an aqueous medium. The apparent molar volume (ϕv0), viscosity B-coefficient, and apparent molar compressibility (ϕk0) values were determined from density, time flow and ultrasonic velocity of lithium chloride in an aqueous solution ϕv and ϕk decreased with increase in concentration and temperature. The values of ϕv and ϕk were obtained from the linear plots of ϕv and ϕk versus C. The other parameters, like intermolecular free length decreases with increase in concentration and temperature, and specific acoustic impedence, relative association arc almost constant with increase in temperature and gradually increases with concentration of solute. All these parameters reveal the importance of hydrophilic part of the solute.
