title: Ionic-strength dependence of formation constants-XII A model for the effect of background on the protonation constants of amines and amino-acids.
abstract: From analysis of literature data on the protonation of N-donor and N,O-donor ligands at 25 degrees , a simple model has been derived for the dependence of amine and amino-acid protonation constants on the background electrolytes, which takes into account the formation of weak complexes between the protonated forms of the amines (or amino-acids) and the background anions and between the amino-acid carboxylate group and alkali-metal cations.
