CORRELATING DESPRETZ CONSTANT WITH LIMITING PARTIAL MOLAL EXPANSIBILITY

The data on temperature of maximum density (TMD) for electrolytes at l ow concentration, subjected to the Debye Hueckel theory to evaluate li miting Despretz constant (K(m)), are used in the present paper to eval uate limiting partial molal exapansibility (E3.98 is-porportional-to) of electrolytes at 3.98-degrees-C and limiting ionic E3.98 is-proporti onal-to which are found to be varying systematically and are more reli able than that evaluated from earlier TMD data and partial molal volum e data given in literature. In fact this is the unique reliable method to evaluate limiting partial molal expansibility (E3.98 is-proportion al-to).
