Abstract: The systems, which are continuously miscible from pure fused ionic solute to dilute solutions in aqueous or non-aqueous phase, exhibit some interesting physical properties. The composition dependence of solvent activity in these systems resembles that of non-electrolyte mixtures. A new equation has been proposed to correlate the solvent activity composition (a1-x1) data for a variety of systems containing fused salts. The proposed equation comprises the contributions due to long-range (a modified Debye-Huckel term) and short-range (an empirical expression) interaction forces. The equation is capable to correlate the solvent activities, a1 for the systems showing strong negative, positive and weak deviations from Rauolt's law. The correlative power of the proposed equation has been tested against 13 systems showing negative deviations, 4 systems showing positive deviations from Rauolt's law and 7 mixtures. These systems are continuously miscible from pure fused salt to dilute solutions. The performance of our equation has been compared to some existing models available in literature.
