| Abstract/Summary |
Proton—monomeric ligand dissociation and metal—monomeric ligand stability constants of 2-acrylamidosulfacetamide (ASA) with some metal ions were calculated potentiometrically in 0. l M-KCl and 40 vol. % 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 ASA and the stability of its formed complexes was studied in monomeric and polymeric forms. The corresponding thermodynamic functions were derived and discussed. The dissociation process is nonspontaneous, endothermic and entropically unfavorable. The formation of the metal complexes has been found to be spontaneous, endothermic and entropically favourable.
