Ion solvation in salt of biologically important rare earth metal with aqueous sugar alcohol (sorbitol) mixed-solvent system

Publication date: Available online 23 January 2017 Source:Journal of Taibah University for Science Author(s): Jayanta Kumar Dash, Susmita Kamila Acoustic investigation have been carried out for the salt of rare earth metal like lanthanum(III) chloride in sorbitol-water mixed solvent system of different concentration at 303.15K temperature and 1 atmospheric pressure. Various parameters have been calculated from the measured values of ultrasonic velocity, density and viscosity data. These parameters shed light on the ion-solvent interaction and also supportive of the structure promoting tendency in the present solute-mixed solvent system. The values of limiting solvation number, S n 0 of lanthanum(III) chloride is maximum in water than in sorbitol-water mixed solvent systems and this is attributed to an interesting outcome regarding the behaviour of sorbitol for water in comparison to other saccharides.
