The thermodynamic parameters for the chelation of cupric ion with 2,2′-dipyridyl have been redetermined at 25°C and I=0.1 M. ΔG values were obtained by potentiometry with a selective ion electrode and ΔH values by direct calorimetry. Similar studies have been made on the relative hydroxocomplexes.

Abstract
The thermodynamic parameters for the chelation of cupric ion with 2,2′-dipyridyl have been redetermined at 25°C and I=0.1 M. ΔG values were obtained by potentiometry with a selective ion electrode and ΔH values by direct calorimetry. Similar studies have been made on the relative hydroxocomplexes. The data obtained are compared with those in the literature and the chelate effect of the heterocyclic diimine is described.File in questo prodotto:
