Abstract (English):
Stepwise dissociation’s constants of α-ketoglutaric ki slots at 298,15 and ionic strength 0,1-2,0 were determined by potentiometric method. As the "background" of the electrolyte potassium chloride is used. The obtained data are extrapolated to zero ionic strength according to the equation with one individual parameter and values of the thermodynamic dissociation’s constants are calculated. The simulation of complex formation in the system Cu(II) - α-ketoglutaric acid-H 2O is carried out. The stability’s constants of forming complex species are calculate.
