| Abstract: | Heat effects of mixing of aqueous solutions of Cu(NO3)2 and L-valine were measured by the calorimetric method at 298.15 K and a ionic strength of 0.5–1.5 (KNO3). The standard heat effects of formation of the Cu(II) complexes with L-valine in an aqueous solution were obtained by the extrapolation to the zero ionic strength using the equation with one individual parameter. The standard thermodynamic characteristics of complex formation in the Cu2+-L-valine system were calculated. |
