Ultrasonic Study of Some Amino Acids in Aqueous Salt Solution of Kno3 at 303.15k

Apparent molar compressibilities (φk) and apparent molar volume (φv) of L-valine, L-leucine andL-phenylalanine in aqueous solution of KNO3 at different concentrations have been determined at the temperature 303.15K using a standard ultrasonic frequency of 2 MHz. The above parameters can be evaluated from precise density, ultrasonic velocity and time flow measurements using a specific gravity bottle, ultrasonic single frequency interferometer and Ostwald type capillary viscometer respectively. With the help of these results various ultrasonic derived parameters such as limiting apparent molar compressibilities (φk o ), limiting apparent molar volumes (φv o ), and their constants (Sk, Sv), viscosity A & B-coefficients and the corresponding transfer parameters (Δφk o , Δφv o and ΔB), have been evaluated. The results have been interpreted in the light of intermolecular interactions between solute and solvent.
