Physicochemical and volumetric properties of of L-isoleucine (ISL) have been studied   in the presence of two electrolytes, potassium chloride (KCl) and sodium chloride (NaCl), at temperatures of 283.15K and 293.15K. The empirically measured physical properties such as density and speed of sound have been utilized for the computation of several parameters such as isothermal compressibility, relative association, non-linier parameter, surface tension, adiabatic compressibility etc., These parameters are interpreted in the context of molecular interactions. Because of the structure-making ability of salt ions and the electrostriction of the solvation shells, it is discovered that the compressibility of the solutions and the solvent decrease with an increase in electrolyte concentration and l-isoleucine amount. The obtained parameters indicate that there is a substantial ion-solvent interaction present in the solution. The results underscored the enhanced ion-solvent interactions, ion-pair formation, and structure-stabilizing effects of L-isoleucine in the presence of KCl/NaCl.
