Method/Apparatus/Procedure:
Ethylene gas was stored in a glass burette equipped with an accurate manometer for measuring pressure and situated in a constant temperature air bath. A known quantity of completely degassed solvent was charged into an equilibrium cell immersed in a liquid bath. The volume of gas absorbed was measured after the gas was admitted into the cell. The solubility was determined from the quantities of gas and solvent used. The apparatus and procedure are described in detail in [1].
Source and Purity of Materials:
- Ethene purity was 99.9 vol. percent.
- Water was bidistilled and had a conductivity of 2 micromhos/cm.
Estimated Errors:
Ambient temperature: δT/K = ±0.01
Mass concentration (m/v) (1): δL/L = ±0.01
Pressure: δP/kPa = ±0.05
