KABILA 1 R. PALANI A. PACHAIKKANNU 1 Department of Physics, D.D.E., Annamalai University, Annamalainagar-608-002 (INDIA) <p style="text-align: justify;">Ultrasonic velocity (U), density (r) and viscosity (h) have been measured for three amino acids viz., L-serine, L-leucine and L-histidine in aqueous magnesium chloride solution at 298.15 K. Using the experimental values, the adiabatic compressibility (&beta;), hydration number (n<sub>H</sub>), apparent molal compressibility (&Oslash;<sub>k</sub>), apparent molal volume (&Oslash;<sub>v</sub>), limiting apparent molal compressibility (&Oslash;<sub>k<sup>0</sup></sub>),&nbsp;limiting apparent molal volume &nbsp;and their constant (S<sub>K</sub>,S<sub>V</sub> ), transfer volume () and viscosity A and B coefficients of Jones-Dole equation were calculated for all the ternary systems. All these results have been interpreted in terms of solute- co-solute and ion-solvent interactions in the given solution.</p> <p>&nbsp;</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1159/ ultrasonic velocity apparent molal volume hydration number transfer volume.
