Method/Apparatus/Procedure:
The experiment was performed in an Ostwald type solubility apparatus consisting of a gas burette and a solubility pipette. The gas burette containing iodomethane and the solubility pipette filled with water were connected and allowed to equilibrate in a thermostat bath. The volume, pressure, and temperature were monitored and Henry's law constants were calculated. A summary of the experiment is given elsewhere (ref. 1).
Source and Purity of Materials:
(1) British Drug House, washed with KOH solution, dried, redistilled and dried again with Ca metal turnings.
(2) Gas free, deionizes by ion exchange resin.
Estimated Errors:
Solubility: ± 0.5 %.
Temperature: ± 0.2 K.
