Complexation of transition metals and α-ketoglutaric acid in aqueous solutions
Potentiometrically studied complexation between cobalt(II), nickel(II) and copper(II) and α-ketoglutaric acid in aqueous solutions. Determined the range of the pH of the complexes existence and their stoichiometry. The dissociation constants of α-ketoglutaric acid and the stability constants of the complexes were calculated.
