title: Potentiometric determination of the protonation constants of 1,3-propanediamine-N,N'-diacetate-N,N'-di-3-propionate.
abstract: The protonation constants of 1,3-propanediamine-N,N'-diacetate-N,N'-di-3-propionate (1,3-pddadp) were determined in sodium nitrate solution of various concentrations and in 0.1M potassium nitrate medium. The values of the thermodynamic functions (DeltaG, DeltaH and DeltaS) for the successive protonation equilibria, in 0.1M (Na)NO(3) medium, at 25 degrees , are also reported.
