Abstract
The interactions between sodium indomethacin and chloride salts of fou r quaternary ammonium compounds were characterized. Investigations inv olved conductimetric studies at concentration regions wherein ion-pair s exist in equilibrium with the solution of participating ions. Iontop horesis was also utilized to investigate the phenomenon of ion-pairing . Characteristic of large molecules, extremely high levels of ion-pair association constants and low degrees of dissociation were obtained.
