Stability constants for metal arsenates

Environmental Chemistry, 2007
Environmental context. The behaviour of arsenic compounds is controlled by their solubility, which in turn controls both the forms and mobility of arsenic in the environment. Current knowledge on arsenic chemistry may be distorted because information available on the solubility of arsenic compounds usually does not include possible formation of metal ...

The stability constant of complex

The International Journal of Applied Radiation and Isotopes, 1980
Abstract The extraction of technetium in reduced valence state from aqueous perchlorate solutions with thenoyltrifluoroacetone in toluene was studied. Values of the reduced technetium partition coefficient in the presence of various concentrations of diethylenetriaminepentaacetate were measured. The dependences of the reduced technetium (labeled with

Constant power load stabilization

Control Engineering Practice, 2018
Abstract Stabilization of constant power loads (CPLs) fed through poorly damped input LC filters involves a trade-off between well damped filter quantities and small generated power modifications, where power modifications in general may be generated by internal CPL power control or by additional hardware.

On the Convergence of Stability Constants

SIAM Journal on Numerical Analysis, 1986
The paper deals with a linear integro-differential equation of order \(m\in N\) under linear boundary conditions \(Lu:=u^{(m)}+L^{(2)}u=f\) in (a,b), \(B_ eu=c_ e\), \(e=1,...,m\). This problem is approximated by a sequence of finite difference equations.

Potentiometric determination of aminal stability constants

Talanta, 1995
Potentiometric titration was used to determine the logarithms of the stepwise equilibrium constants for the species formed between morpholine and formaldehyde in aqueous solution, ionic strength 0.5 and 2.5M (KCl) at 25 degrees C. The instrumental and computational techniques developed for metal-ligand stability constant determination were applied ...

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 ...

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 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 Internal Complexes

Nature, 1947
APART from the results of a series of studies dealing with complexes of copper, little is known of the stability of internal complexes. Calvin and his collaborators1 have found wide variation in the stability of complexes of copper formed from a series of I diketones and o-hydroxy-aromatic aldehydes.

Prediction of Stability Constants

2010
Stability constants of complex compounds depend on many factors, thus many methods and approaches are used for their prediction. Here we give an overview of these methods starting from simple Irving-Williams order and HSAB model. Next we present various correlations of stability constants of complexes to each other and to protonation constants of the ...
