The stability constant of Pd-EDTA

Talanta, 1978
The literature value of the stability constant of the palladium-ethylenediaminetetra-acetate complex (log K(Pd-EDTA) = 18.5), is open to question. From replacement experiments with thorium a value log K(Pd-EDTA) = 26.4 has been found. This value is in better agreement with experimental facts from protonation studies at low pH and with the fact that ...

The comparison of stability constants

Journal of Chemical Education, 1968
In some texts, the stability of complexes with polydentate ligands is done incorrectly by comparing the numerical value of the stability constant with the numerical value of the overall constant of...

Stability Constants and Their Measurement

1996
The equilibrium constant involving the formation of a metal complex from the aquo metal ion and the most basic form of the ligand is a standard measure of the effectiveness of the ligand in coordinating metal ions. The constants involved are called stability constants or formation constants.

Stability constants of aluminium fluoride complexes

Talanta, 1971
Pointwise titrations of aluminium nitrate solutions with sodium fluoride were made at ionic strengths of 0.5, 0.2, 0.1 and 0.05M and at temperatures of 25 degrees and 37 degrees . The total Al(3+) concentration was kept constant at 5 x 10(-4)M and the total F(-) concentration covered the range 5-20 x 10(-4)M with a minimum of 20 points per titration ...

Conditional Stability Constants

2012
The introduction of conditional stability constants permits us, from a theoretical standpoint, to treat a complexation equilibrium to which are superimposed other equilibria of any nature as if it were alone, at least in some conditions. Conditional stability constants were introduced by G.

Stability constant for the zinc-dithiothreitol complex

Analytical Biochemistry, 1972
Rat liver histidase is competitively inhibited by a variety of compounds that are good complexing agents for Zn+2. Dithiothreitol is a strong competitive inhibitor, but 20 μM Zn+2 completely reverses the inhibitory action of 1.7 mM dithiothreitol. Effectiveness of inhibitors is directly related to the stability constants (Kst) for the corresponding ...

On an Absolute Constant in the Theory of Variational Stability

American Journal of Mathematics, 1937
this equation being the characteristic equation of a real binary linear substitution of determinant 1. If A is not a multiple of Tiri, it is clear that the two solutions (2) are linearly independent. If X is a multiple of Tiri, it depends on the elementary divisors of that binary substitution whether or not the general solution of (1) is free of ...

Stability constants of some metal dithizonates

Talanta, 1973
The overall stability constants of electroneutral dithizonates of bismuth, cadmium, cobalt(II), copper(II), iron(II), lead(II), manganese(II), mercury(II), nickel, palladium(II), silver, tin(II) and zinc were determined by means of stoichiometric dilution in aqueous solution stabilized by hydroxylamine hydrochloride, at pH 5.50-10.02.

Determination of the Stability Constants of Tetracycline Complexes

Journal of Pharmaceutical Sciences, 1965
The Bjerrum ΔKOH method for determining the degree of formation ( n ¯ ) from the titration curves of a ligand with and without metals is derived without approximations. The Calvin and Wilson method is rederived in a form which allows easy comparison between the values calculated by each method.

The stability constants of TAR and PAR complexes

Talanta, 1967
A discussion is given of the problem of ascribing dissociation constants in the hypothetical situation in which the protons of the hydroxy groups of TAR and PAR dissociate in the reverse of the normal order, and it is suggested that the o-hydroxy group should be regarded as intrinsically as acidic as the p-hydroxy group, and that the change in pK due ...
