Abstract
The formation constants of the Ca2+ and Mg2+ complexes with 2-hydroxypropyl ene-1,3-diamine-N,N,N',N'-tetraacetic acid were determined by potentiometri c titration [25 degrees C, ionic strengths 0.1, 0.5, 1.0 (KCl)]. The result s are extrapolated to the zero ionic strength of the solution using the equ ation with one individual parameter. The stability of related compounds is discussed with allowance made for the specific features of ligand coordinat ion.
