Methodology:
The method was essentially that employed Eucken and Herzberg [1]. The solvent was degassed by alternately opening to the vacuum pump for 5-15 s and then stirring very rapidly to produce cavitation. This was repeated 5-10 times. In the solubility measurement itself gas, which had been previously saturated with solvent vapor, was admitted to the saturation vessel, holding about 80 mL of solution, and with 5-10 mL remaining space, volume-time measurements were taken and extrapolated back to the time the gas was admitted. Then the stirrer was turned on and driven very fast, producing a slightly (~1%) supersaturated solution. The approach to equilibrium was then followed from each direction while stirring as rapidly as possible without producing cavitation and bubbles.
Sample Information:
- Source not specified; purity not specified; redistilled and dried by filtering at $\pu{-20^{\circ}C}$.
- Krypton, neon and xenon were reagent grade products of the Air Reduction Co.; purity $\pu{99.8 w/w\%}$; nitrogen was purified by passing over $\ce{CaH2}$ and $\ce{CaO}$.
Measurement Errors:
Mass concentration (m/v) (1): relative error of 2 to 3 determinations less than 3%.
