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.
- Heparin was used as a blood anticoagulant.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δL/L = ±4% (compiler)
Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
- Dog blood,
- Dog plasma,
