dc.description.abstractThe dissolution enthalpy of sodium sulfacetamide water was determined by means of isoperibolic solution calorimetry. It was found that diminishes as the drug concentration increases. Otherwise, the calorimetric values obtained as a function of the drug concentration were significantly different than those predicted by the van’t Hoff method. It was demonstrated that the later is not a fully reliable method for the determination of values in the specific case of highly soluble sodium salts. The observed phenomenon could be explained by the presence of strong solute-solute interactions at high salt concentrations, in addition to solute-solvent and solvent-solvent interactions.
