Conditions:
Room Temp:
273.15 - 298.15
$\pu{K}$
Pressure:
1.013 - 4.560
$\pu{MPa}$

Methodology:
Rocking equilibrium cell fitted with Bourdon-type pressure gauges. Carbon dioxide gas admitted to cell containing water. After equilibrium established samples of liquid withdrawn and analyzed by stripping out carbon dioxide, absorbing in excess barium hydroxide and back-titrating.
Sample Information:
- Matheson research grade, purity 99.99 mole%.
- Degassed and distilled.
Measurement Errors:
Ambient temperature: δT/K = ±0.06
Mass concentration (m/v) (1): δx1/x1 = ±1%
Pressure: δP/kPa = ±2 below 3.6 MPa, ±3.4 above 3.6 Mpa
System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
