Volumetric study of strong electrolytes-Metal chlorides and metal sulphates in aqueous medium at different temperatures

Bidyadhar Swain*, Rabindra N.

Abstract

The apparent molar volume (Vф) of strong electrolytes like Magnesium chloride, Zinc chloride, Strontium chloride, Cadmium chloride, Barium chloride, Magnesium sulphate and Zinc sulphate has been evaluated from the density data of their aqueous solutions at 298.15, 303.15, 308.15 and 313.15K. The apparent molar expansibility (Eф) has been calculated from the apparent molar volume at these temperatures. The limiting apparent molar volume(Vф 0),limiting apparent molar expansibility (Eф 0) and the constants (SV and SE) have also been evaluated and discussed in the light of solute-solvent and solute-solute interactions .
