DETERMINATION OF PARTIAL MOLAR PROPERTIES AND ACOUSTIC PARAMETERS OF AMINO ACIDS IN AQUEOUS METHANOL SOLUTIONS IN PRESENCE OF SODIUM BENZOATE
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2014, Vol 6, Issue 10
Abstract
Objective: To study the partial molar properties and acoustic parameters of amino acids in the solutions of 5, 10 and 15 wt %of aqueous methanol in presence of sodium benzoate.Methods: Effect on solute –solvent interaction is studied by determining the densities of pure solvents and the ultrasonic velocity of pure solvent and solutions is measured by using an ultrasonic interoferometer.Results: The results are discussed in the light of molecular interaction, ion-solvent interactions ion-solvent interactions dominate over ion-ion interactions, β-alanine has higher ion-solvent interaction than α-alanine & glycine.Conclusion: Overall,β-alanine shows high ion-solvent interaction due to higher mass which represents structural effect of solute on solvent in solution.Â
