Glass Ball as Bullet Solubility System: Hexane with Seawater

Components:
   (1) Hexane; C6H14; [110-54-3]  NIST Chemistry WebBook for detail
   (2) Seawater; ; []  NIST Chemistry WebBook for detail

Evaluator:
   D.G. Shaw, Institute of Marine Science, University of Alaska, Fairbanks, Alaska USA. December 1982.

Critical Evaluation:

   The solubility of hexane (1) in seawater (2) at 298 K has been reported in two works:

These two determinations were made at somewhat different salinities and thus cannot be directly compared. Because the presence of sea salts is expected to depress the solubility value below the value for pure water (tentative value 1.3 x 10-3 g(1)/100 g s1n) the tentative value of 7.86 x 10-4 g(1)/100g s1n is adopted for hexane in seawater at the indicated temperatures and salinity. The value of Krasnoshchekova and Gubergits is considered doubtful. Freegarde et al. (ref 3) also measured the solubility of hexane in seawater. However, since they did not report temperature or salinity, their work is rejected. Aquan-Yuen et al. have also measured solubility over a range of salinities.
