摘要
The complex formation between silver(I) and nicotinamide as well as between copper(II) and nicotinamide in water-ethanol and water-dimethylsulfoxide media was studied by means of potentiometric technique. The heat of complex formation was measured using the method of precision calorimetry. The experimental data have been considered from the point of view of thermodynamic characteristics of the reagents and their solvation. (C) 2008 Elsevier B.V. All rights reserved.
