Abstract | ||||
Proton-monomeric ligand dissociation and metal-monomeric ligand stability constants of Acrylonitrile (AN) with some transition metal ions were calculated potentiometically in 0.1 M KCl and 50% (v/v) ethanol water mixture. Also, in the presence of 2,2-Azobisisobutyronitrile as initiator the proton-polymeric ligand dissociation and metal-polymeric ligand stability constants were calculated. The effect of temperature on the dissociation of (AN) and the stability of its formed complexes were studied in monomeric and polymeric forms. The corresponding thermodynamic functions were derived and discussed. The dissociation process is non-spontaneous, endothermic and entropically unfavorable. The formation of the metal complexes has been found to be spontaneous, endothermic and entropically favorable. | ||||
