Glass Ball as Bullet Solubility System: Hexane with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Hexane; C6H14; [110-54-3]  NIST Chemistry WebBook for detail
Original Measurements:
   Booth, H.S.; Everson, H.E., Ind. Eng. Chem. 1948, 40, 1491-3.

 Variables:
   Temperature = One temperature: 25.0 °C (298.2 K)

 Prepared By:
   G.T. Hefter

 Experimental Remarks:
   The solubility of n-hexane in water at 25.0 was reported to be <0.04 mL (1)/100 mL (2).

A similar result was reported for (1) in 40.0% (w/w?) aqueous sodium xylenesulfonate.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   A known volume of water, typically 50 mL, was placed in a stoppered Babcock tube having a neck graduated from 0 to 1.6 mL in steps of 0.02 mL. An excess of solute was added and the mixture allowed to come to equilibrium in a constant temperature bath then centrifuged. The amount of solute dissolved was determined by subtracting the undissolved solute, measured directly in the tube, from the total added.

 Source and Purity of Materials:
   (1) "Highest grade commercial sample available"; no other details given.
   (2) Distilled.

 Estimated Errors:

   Temperature: Not specified.
