Abstract
The study presents the saturated solubilities of four amino acids such as glycine, dl-alanine, dl-valine, and dl-serine in water media containing sodium bromide and potassium bromide electrolytes at standard temperature (298.15 K) which were evaluated by applying the “gravimetric method”. Various physicochemical and thermodynamical parameters such as enthalpy of solvation, free energy change, density, molar volume, solvent diameter, cosolvent diameter, apparent dipole moment of aqueous electrolyte systems, mole fraction of salt and solvent, mean molecular weight of electrolyte solvent and isothermal expansibility constant of aqueous electrolytes were estimated at standard temperature (298.15 K). The characteristics and degree of solubilities of the experimental molecules in water media in the presence of NaBr and KBr were examined by means of the salting-in effect which was further justified by relative solubility and salting-in constants. Various reasonings influencing the solubility were introduced and ...
