摘要：
Thermodynamic constants of the stability of coordination compounds and their thermodynamic potentials of complexation in water solutions at 298 K are determined. Kinetic characteristics of the complexation reaction between calcium ions and amino acids in water solutions at 298 K are calculated. The ability of calcium ions to coordinate different amino acids as ligands is shown, and a tendency in the complexation of amino acids with different structures is established. Coordination compounds are studied via potentiometric titration using mathematical means of treating data.
