| Abstract: | A general equation is derived for predicting the partial molal volume (pmv) of an electrolyte in seawater, using binary solution data, and seawater density data. The composition of seawater need not be “average” - prediction can be made for any composition. Simpler equations are derived for “average” seawater. The ranges cover , t = 0–30°C and p = 1–1,000 bar, subject to the availability of binary solution data. Estimates of the pmv's of a number of electrolytes are made and compared with experimental values and the summed ionic values. |
