Original Measurements
Novák, J. P.; Fried, V; Pick, J.; Collect. Czech. Chem. Commun. 1961, 26, 2266-70.
Variables:
Room Temp:
284.65 - 350.15
$\pu{K}$
Pressure:
12.8 - 97.5
$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
Saturation method. Five cylinders containing water were saturated with $\ce{CO2}$ in a thermostat at the pressure of measurement. No stirrings was provided. Samples were withdrawn at constant pressure and titrated. Details in source.
Source and Purity of Materials:
- Tank quality. Light gases were distilled.
- Distilled.
Estimated Errors:
Ambient temperature: δT/K = ±0.1
Mass concentration (m/v) (1): δx = ±1%
Pressure: δP/kPa = ±0.07
Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
