Method/Apparatus/Procedure:
A glass bubbling-type of saturator immersed in a constant temperature bath was used. A known volume of saturated solution was transferred over mercury into a Van Slyke desorption apparatus. Gas removed in three evacuations was transferred to a sample tube where the volume was determined and a sample of the gas was analyzed. Solubilities were determined at several pressures below atmospheric and above atmospheric and expressed as Ostwald coefficients.
Source and Purity of Materials:
- Ethene source and purity not given.
- Water distilled.
Estimated Errors:
