Method/Apparatus/Procedure:
Cell charged with components, equilibrated and pressure measured with Bourdon gauge. Liquid sampled and analyzed by stripping with nitrogen and absorbing dried carbon dioxide on absorbent containing sodium hydroxide.
Source and Purity of Materials:
- Lachema, Novy Bohumin sample purity better than 99.8 mole%.
- Redistilled sample, purity probably better than 99 mole%. (compiler)
Estimated Errors:
Ambient temperature: δT/K = ±0.1 (estimated by the compiler)
Mass concentration (m/v) (1): δx1 = ±0.2 × 10-4 (estimated by compiler)
Pressure: δP1/bar = ±0.5 (estimated by compiler)
Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Water-d2, $\ce{ D2O }$; [7789-20-0] NIST WebBook
