Method/Apparatus/Procedure:
The measuring apparatus was described by Brown
et al.
(ref. 1). Iodomethane gas was admitted to the measurement apparatus from a storage bulb by distillation. The gas volume absorbed by heavy water was determined in the gas buret. The temperature was controlled by a water bath and the equilibrium was aided by a magnetic stirrer in the equilibration bulb. The concentration of the solution was calculated from the pressures and volumes measured.
Source and Purity of Materials:
(1) Eastman Kodak Co., redistilled before use.
(2) Liquid Carbonic Co., 99.5 % pure, used as received.
Estimated Errors:
Solubility: ± 3 %.
Temperature: ± 0.01 K.
Pressure: ± 0.05 mmHg.
