Abstract: By means of potenriometric pH measurements, the acidity constants of 1,4-diaminobutane and 1,5-diaminopentane have been determined in 1.0 M KNO3 at 25.0 degrees C. Combined pH/pAg data were used at the same temperature in aqueous 1.0 M KNO3 to study the complexation of Ag(I) with the diamines. Protonated and non-protonated mononuclear and polynuclear complexes were detected. No evidence was found for the existence of hydroxo complexes. The resulting overall stability constants have been compared with previously determined stability constants for Ag(I)-ethylenediamine and Ag(I)-1,3-propylenediamine complexes. Some relationships concerning the length of the CH2 backbone have been identified.
