Method/Apparatus/Procedure:
The measuring apparatus was described by Brown, et al. [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:
- Eastman Kodak Co., redistilled before use.
- Liquid Carbonic Co., 99.5% pure, used as received.
Estimated Errors:
Ambient temperature: ±0.01 K.
Mass concentration (m/v) (1): ±3%.
Pressure: ±0.05 mmHg.
