Abstract: | The formation and stability of Li+, Na+ and K+ complexes with oxalate, malonate, succinate, maleate, DL-malate and phthalate were studied potentiometrically at various ionic strengths. From the data thus obtained, as well as from several literature data on the protonation of the above-mentioned ligands in various ionic media and at various temperatures, the dependence of Na+ and K+ complex formation on temperature was determined. The dependence on ionic strength, both for the protonation and the complex formation, is also discussed. |
