Infinite Dilution Partial Molar Volumes of Aqueous Solutes over Wide Ranges of Conditions

摘要

Data for the partial molar volume at infinite dilution for several gaseous solutes and H_3BO_3 in water have been correlated using a generalized Krichevskii parameter. The result is a simple function for v_1~∞ in terms of the water density and compressibility for conditions from ambient to 725 K and 40 MPa. The accuracy is much better with only two parameters than with a previous five-parameter model.
