Methodology:
All-glass apparatus. The total pressure was kept constant during equiliration. The equilibration cell was shaken in a constant temperature bath. After equilibration, a liquid sample was volumetrically analyzed for solution and $\ce{CO2}$ content.
Detailed description given in the original source.
Sample Information:
- "Pure". Saturated with water vapor.
- Analytical grade.
- Distilled.
Measurement Errors:
Mass concentration (m/v) (1): δα = ±0.005 (by author)
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Electrolyte (saturated),
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Total pressure P in the measurements was 783.5 mmHg (104.46 kPa, 1.045 bar), and temperature 25°C (298.15 K).
