Methodology:
The prepared solvent and solution were charged into an evacuated cell after degassing, and the mass of solvent was determined by weight. Gas was introduced into the cell from a measuring buret in which the gas was stored over mercury. The cell was agitated while the gas pressure was maintained by adjusting the gas volume. The Ostwald coefficient was determined from the mass of solvent and the volume of gas absorbed. Solubilities were measured at pressures above and below atmospheric.
Sample Information:
- Source and purity not given. An aqueous "soda" solution absorbed 99.8% of the gas.
- Source and purity not given. Recrystallized from water and dried.
- Boiled to remove carbon dioxide.
Measurement Errors:
Ambient temperature: δT/K = ±0.2
Mass concentration (m/v) (1): δL/L = ±0.02 (compiler)
Pressure: δp/kPa = ±0.1
