Glass Ball as Bullet Solubility System: p-Cymene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) p-Cymene; C10H14; [99-87-6]  NIST Chemistry WebBook for detail
Original Measurements:
   Booth, H.S.; Everson, H.E., Ind. Eng. Chem. 1948, 40, 1491-3.

 Variables:
   Temperature = 25 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of p-cymene in water at 25°C was reported to be 0.04 g(1)/100 mL(2). Assuming a solution density of 1.00, the mass percentage and mole fraction, x1, calculated by the compilers are 0.04 g(1)/100 g sln and 5 × 10–5.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Stoppered Babcock tubes with neck graduated from 0 to 1.6 mL in steps of 0.02 mL were used. A known volume of (2) (generally 50 mL) was added to the tube in a constant-temperature water bath and weighed quantities of (1) were added to this solution. The mixture was then shaken for 5 minutes, returned to the bath for a minimum of 10 minutes and then centrifuged for 5 minutes. After this treatment, this volume of residue was determined directly.

 Source and Purity of Materials:
   (1) source not specified; CP or highest commercial grade; used as received.
   (2) distilled.

 Estimated Errors:
   Solubility: ± 0.1 mL (1)/100 mL (2).
