Method/Apparatus/Procedure:
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.
Source and Purity of Materials:
- Commercial sample, minimum purity 99.8 mole%.
- Analytical grade.
- Distilled and degassed.
Estimated Errors:
Ambient temperature: δT/K = ±0.2 (estimated by the compiler)
Mass concentration (m/v) (1): δα = ±2% (estimated by the compiler)
Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Sodium hydrogen sulfite, $\ce{ NaHSO3 }$; [7631-90-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
