Stability of New Zinc Complexes with β,βʹ-(Ethylenediamine)-N,N-dipropionic Acid

Stability constants of new zinc complexes with β,βʹ-(ethylenediamine)-N,N-dipropionic acid: dichloro[β,βʹ-(ethylenediamine)-N,N-dipropionato]zinc and [β,βʹ-(ethylenediamine)-N,N-dipropionato]zinc hydrate were determined by potentiometric titration (Bjerrum’s method) using an unconventional approach in the case of the first complex.
