Abstract: | The stability constants of complexes of dioxovanadium (V) ion and L-asparrtic acid were determined potentiometrically at various
ionic strengths of I = 0.1, 0.3, 0.5, and 0.7 mol. dm−3 at 25°C. A sodium chloride solution was used to maintain the ionic strength. The parameters based on these formation constants
were calculated and the dependence of protonation and the stability constants on ionic strength are described by a Debye-Huckel
type equation. |
