Relation between stepped constants of instability of complex compounds

Relations between step unstgbility constants of complex compounds: pKsub(n)=αsub(n)pKswb(1)+βsub(n) and pKsub(n+1)-pKsub(n)=α'sub(n)pKsub(1)β'sub(n) were obtained on the basis of chemical thermodynamics extended on the reactions of complex particles interaction in the electrolytic solutions. The validity of correlations was supported by experimental data on step unstability constants values for 88 metal-ligand systems taken from the reference literature. The possibility of calculating αsub(n), αsub(n), βsub(n) i βsub(n) parameters was demonstrated
