Abstract

Protonation and stability constants for the title complexes were determine pH-metrically at 25?and ionic strength 0.1 (KNO3). The nature of metal ion coordination in these chelates is discussed. An acid dissociation equilibrium scheme is presented for the title ligand.

Key words: STABILITY, ALKALINE EARTH METAL, ZINC COMPLEX, URANYL COMPOUNDS, IRON COMPLEX, COPPER COMPLEX, COBALT COMPLEX, NICKEL COMPLEX, ACETIC ACID P, DISSOCIATION EQUILIBRIUM
