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<sup>-1</sup> at 303 K. From these data, adiabatic compressibility (<img src='' border=0>), change (<img src='/image/spc_char/delta.gif' border=0><img src='' border=0>), relative change in adiabatic compressibility (<img src='/image/spc_char/delta.gif' border=0><img src='' border=0>/<img src='' border=0><sub>0</sub>), acoustic impedance (<i>Z</i>), limiting apparent molar compressibility (<img src='/image/spc_char/phi.gif' border=0><sub>k</sub>), limiting apparent molar volume (<img src='/image/spc_char/phi.gif' border=0><sub>v</sub>) and their constants <i>S</i><sub>k</sub> and <i>S</i><sub>v</sub> 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.
