DETERMINATION OF PARTIAL MOLAR PROPERTIES AND ACOUSTIC PARAMETERS OF AMINO ACIDS IN AQUEOUS METHANOL SOLUTIONS IN PRESENCE OF SODIUM BENZOATE
Keywords:
Amino-acids, Methanol, Ultrasonic velocity, Solvation number, Sodium benzoateAbstract
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.
