ABSTRACT
Speeds of sound of (l-alanine/l-glutamine/glycylglycine +0.512mol*kg -1 + 0.512 mol * kg - 1 aqueous KNO 3 /0.512mol*kg -1 KNO 3 / 0.512 mol * kg - 1 aqueous K 2 SO 4 K 2 SO 4 ) systems have been measured for several molal concentrations of amino acid/peptide at different temperatures: T T = (298.15 to 323.15) K. Using the speed-of-sound and density data, the parameters, partial molar isentropic compressibilities ? 0 ? ? ? 0 and transfer partial molar isentropic compressibilities ? tr ? 0 ? ? tr ? ? 0 , have been computed. The trends of variation of ? 0 ? ? ? 0 and ? tr ? 0 ? ? tr ? ? 0 with changes in molal concentration of the solute and temperature have been discussed in terms of zwitterion ion, zwitterion water dipole, ion water dipole, and ion ion interactions operative in the systems.
