Method/Apparatus/Procedure:
Concentrated solution prepared by weighing, less Concentrated solution prepared by weighing, less concentrated solutions prepared by subsequent dilution. Equilibrium established between a measured volume of gas and a measured amount of gas-free liquid in a cell fitted with a magnetic stirrer. Amount of gas absorbed estimated from change in volume of gas. Details in source and [1].
Source and Purity of Materials:
- Commercial sample, purity 99.6 mole%.
- Analytical grade sample.
- Analytical grade sample.
