摘要: The ligand dissociation constants and the formation of Cu(II) piperidine-2-carboxylic acid chelates have been measured in varying proportions methanol-water, ethanol-water, acetone-water, isopropanol-water dioxane-water at 30°C 0.10 M ionic strength. results are discussed with reference to change dielectric constant water presence organic solvent, structure hydrogen bonding water, relative solvent basicity proton solvation by solvent. relatively greater contribution stability metal chelate O-M link as compared N-M has suggested on basis observed effects stabilities.
