Glass Ball as Bullet Solubility System: Iodomethane with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Iodomethane; CH3I; [74-88-4]  NIST Chemistry WebBook for detail
Original Measurements:
   Hunter-Smith, R.J.; Balls, P.W.; Liss, P.S., Tellus 35B, 170 (1983).

 Variables:
   Temperature = 283 K - 298 K

 Prepared By:
   A. L. Horvath

 Experimental Remarks:
   The Henry's law constant (H) was derived from the best-fit lines of van't Hoff plots:

loge H=-3541/T(K) + 10.34

Experimental Data:   (Notes on the Nomenclature)
  

t/°CHenry's law constant [(dimensionless)]102 * Mass Fraction w1 (compiler) 103 * Mole Fraction x1 (compiler)
100.11471.53171.971
150.14251.49821.927
200.17571.46451.883
250.21511.43081.839
 Method/Apparatus/Procedure:
   The multiple equilibration technique as described elsewhere (ref. 1) was used to measure the Henry's law constants. A known volume of water in a syringe was shaken with a known volume of pure iodomethane. After equilibration, the headspace was separated  and analyzed for the compound of interest. A gas chromatograph fitted with an electron capture detector was used for the analysis.

 Source and Purity of Materials:
   (1) Source and purity not given.
   (2) Distilled.

 Estimated Errors:

   Temperature: ± 0.2 K.
