Methodology:
Concentrated solution prepared by weighting, less concentrated solutions prepared by dilution. Equilibrium established between a measure 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].
Sample Information:
- Commercial sample, purity 99.8 mole%.
- analytical grade sample.
- No details given.
Measurement Errors:
Ambient temperature: δT/K = ±0.2 (estimated by the compiler)
Mass concentration (m/v) (1): δα = ±2% (estimated by the compiler)
