Original Measurements
Bohr, C.; Bock, J.; Ann. Phys. Chem. 1891, 44, 318-43.
Variables:
Ambient temperature: 310.44 and 373.15 K
Pressure: 94.3 kPa and 85.7 kPa

Method/Apparatus/Procedure:
An all-glass apparatus was used. The system was equilibrated by bubbling gas through thermostatted water.
The solubility was measured in two different ways: by considering the amount of dissolved gas which disappeared from the vapor phase, and by volumetric analysis of the gas removed from a liquid solution sample.
