COMPLEX-FORMATION OF NICKEL (II) WITH GLYCINATE- AND ACETATE-IONS, ACIDIC-BASIC EQUILIBRIA IN AQUEOUS-ORGANIC SOLVENTS

By Vera Alexandrovna Isaeva

Abstract

There the paper purposes are to study the reactions of complex-formation of nickel (II) with the charged mono- and bidentant ligands, which contain the donor atoms of oxygen, to learn the acidic-basic equilibria of ligands in mixtures of water with the solvents of different classes. The stability constants of acetate and glycinate complexes of nickel (II) and of acidic-basic equilibria of ligands, the thermal effects of dissociation reactions of glycine-ion in the aqeous-organic solvents have been determined for the first time. The mechanisms in change of thermodynamical characteristics of reactions of complex-formation of nickel (II) with charged ligands and in solvation of reagents have been ascertained. The obtained results may be foundations to compute the equilibria with the analytical purpose, to develop and to optimize the processes with the assistance of carbonic and aminocarbonic acids as well as may be used as the reference materialAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
