Original Measurements
Morrison, T. J.; Billett, F.; J. Chem. Soc. 1952, 3819-3822.
Variables:
Room Temp:
286.45 - 347.85
$\pu{K}$
Pressure:
101.325
$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
An improved apparatus for solvent pretreatment was used [1]. The gas content in the solution was analyzed with a gas burette. The solvent was equilibrated by flowing a liquid film through the gas. No supersaturation was observed.
Source and Purity of Materials:
- Prepare from marble.
The system was sealed to prevent contamination with air. - Pure. Degassed.
Estimated Errors:
Ambient temperature: Not stated.
