Densities and speeds of sound of L–valine in aqueous sodium bromide solutions at various temperatures
T Sumathi, K Jetruth Mary Alphonsa
Abstract :
Ultrasonic speed (U), density (ρ) and viscosity (η) values for ternary systems (amino acid+ salt+ water): L–valine in aqueous solutions of 0.0M, 0.025M, and 0.050M sodium omide have been measured for several concentrations of amino acids at different temperatures (303, 308 and 313K). From these experimental data, derived thermodynamic parameters such as the adiabatic compressibility (β), change in adiabatic compressibility (Δβ), relative change in adiabatic compressibility (Δβ/ β0), acoustic impedance (Z) and relative association (Ra) have been computed using the standard relations. The results have been interpreted in terms of various intermolecular/interionic interactions existing in the systems
