Correlation of Properties of Aqueous Electrolyte Solutions

Effects of Molality of Electrolyte on Vapor Pressure, Boiling Point Elevation and Heat of Vaporization

Abstract

The vapor pressure of water over the solutions containing 1.516-5.415mol/kg magnesium iodide was measured up to about 4,000mmHg by the direct static method. On the basis of the present and five reported data (NaOH, Na₂CO₃, NaCl, NaClO₃ and LiBr) determined in a wide concentration range, the vapor pressure, boiling point elevation (B.P.E.) and heat of vaporization for aqueous electrolyte solutions were correlated to the solute concentration by using an empirical equation.
