Thermodynamics of the Formation of Complexes of Nickel(II), Triglycine, and L-Histidine in Aqueous Solutions

Аннотация

The Ni²⁺–triglycine–L-histidine system is studied by potentiometric and calorimetric means in aqueous solutions at Т = 298.15 K (KNO₃). The formation of mixed ligand complex NiLY is registered, and standard thermodynamic characteristics (Δ_rH°, Δ_rG°, Δ_rS°) of its formation are determined. A structure of the complex is proposed.
