Abstract
Heat effects arising from interactions between triglycine solutions and Cu(NO3)2 solutions are studied at 298.15 K and ionic strengths of 0.2 to 1.0 (KNO3) via isothermal calorimetry. Using experimental data, enthalpies of formation are calculated for species CuH−1L, CuH−2L−, and CuH−3L2−, along with ΔrH°, ΔrG°, and ΔrS° of the complexation process. A relationship is revealed between the structures of deprotonated single-ligand triglycine complexes of Cu(II) and the thermodynamic parameters of their formation.
