| Abstract: | Density, speed of
sound and viscosity data for 2-amino 3-phenyl propanoic acid commonly known as
phenylalanine in aqueous sodium chloride (NaCl), potassium chloride (KCl) and
lithium chloride (LiCl) have been measured in the concentration range 0.00-0.10
mol.kg-1 at 303 K.
From these data, adiabatic compressibility ( ), change ( ), relative change in adiabatic compressibility (/0),
acoustic impedance (Z), limiting apparent molar compressibility ( k), limiting apparent molar volume (v) and their constants Sk
and Sv have been computed. The observed variation of these
parameters helps in understanding the nature of solute-solvent interactions
present in the system. The structure-breaking capacity of phenylalanine has
been inferred from aqueous electrolytes using Jones-Dole equation. |
