Evaluation of limiting molar conductance, Walden product, association constant and thermodynamic properties of sulfacetamide sodium in water + EtOH mixtures

► Ion solvation behavior of Sulfacetamide sodium in water and water-ethanol mixtures. ► Kraus-Bray and Shedlovsky models of Conductivity. ► The limiting molar conductance decreases with increase in the amount of ethanol. ► Maxima in the Walden product near 0.3 volume fraction of ethanol in water.
