Glass Ball as Bullet Solubility System: Pentachlorophenol with Water
Components:
   (1) Pentachlorophenol; C6HCl5O; [87-86-5]  NIST Chemistry WebBook for detail
   (2) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Blackman, G.E.; Park, M.H.; Garton, G., Arch. Biochem. Biophys. 1955, 54(1), 55-71.

 Variables:
   Temperature = One temperature

 Notes:
   a  Calculated by F. W. Getzen.
   b  Reported value measured at pH 5.1.

 Method/Apparatus/Procedure:
   The samples were equilibrated in a thermostat bath with intermittent shaking over periods of 3-4 weeks. During the equilibration time, the pH values of the solutions were controlled by dropwise addition of phosphate buffer solution. The analysis of the solute concentration in the saturated samples was done spectrophotometrically either directly or by using proper colorizing agents.

 Source and Purity of Materials:
   (1) Probably a commercial reagent.
   (2) Distilled water.

 Estimated Errors:
   Solubility: <5% (evaluated on the basis of the reported results of the two techniques of analysis).
