Methodology:
Solutions made up by weight and density measured but not reported in paper. 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.
Sample Information:
- Commercial sample, minimum purity 99.8 mole%.
- Analytical grade.
- Distilled and degassed.
Measurement Errors:
Ambient temperature: δT/K = ±0.2 (estimated by the compiler)
Mass concentration (m/v) (1): δα = ±2% (estimated by the compiler)
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Barium chloride, $\ce{ BaCl2 }$; [10361-37-2] NIST WebBook
