Abstrakt: Constants of the stepwise dissociation of ethylenediamine-N,N'-bis(α-propionic) and ethylenediamine-N,N'-bis(β-hydroxy-α-propionic) acids are determined via potentiometric titration at 298.15 K and values of ionic strength of 0.1, 0.5, and 1.0 (KNO3). The obtained data are extrapolated to zero ionic strength using an equation with one individual parameter, and the values of thermodynamic constants of dissociation are calculated.
