Abstract:
Potentiometric equilibrium studies have been made at 20, 25, 30, 35, 40°C for benzoylacetanilide (BAA), acetoace-tanilide and their neodimium (III) chelates in nonaqueous medium. The dissociation constants of these ligands were computed as well as the stability constants of their neodimium 1;1 chelates at different ionic strengths and temperatures. The free energy, G, the enthalpy, H and the energy change, S, for the process of the dissociation of such ligands and the formation of their Nd(111) chelates are reported in 70% (v/v) ethanol-water mixture and O.IM KNO3, ionic strength.
