We illustrate the kind of behaviour of the stability constant
0] is the distribution constant in the absence of HA/FA, [lambda] is the distribution constant in the presence of HA/FA, logK is stability constant
of arsenate-HA/FA complex, x is number of moles of HA/FA that combine with 1 mole of arsenate, and [HA] is concentration of HA/FA in moles per L.
Thermodynamic quantities have been derived from overall stability constants
: Stability constant
and Themodynamic parameters for M(II)-Thymidine complexes in aqueous media at ionic strength 0.
Measurement and calculation of the PDCA stability constants
of calcium and magnesium ions
Table 7 records the values of x (number of mol HA/FA that combine with 1 mol arsenic) as well as logK (where K is the stability constant
of arsenic-HA/FA complexes).
Recently Buschmann has shown that the determination of the total concentration of a ligand in a salt solution by using UV-Vis spectroscopy allows the determination of the stability constant
of the complex formed in solution.
2] where the authors investigated the stability constants
of acrylic acid based cuprates complexes by adopting the method of Bjerrum .
In the calculated stability constant
, the metal concentration was 0.
In general, the stability constants
of trivalent ions such as Al are higher than those of divalent ions such as Ca for complexes with carboxylate ligands, but their relative magnitude varies widely (Martell and Smith 1977; Tam and Williams 1984), so that in considering the effect of organic structure on the effectiveness of the organic additive (see Hue et al.
This chelating agent has a large stability constant
with Fe 3+ metal ligand (logKML = 19.
The products are formed in ratio of 1:1 and the stability constants
H] is the conditional stability constant
