Original Measurements
Takenouchi, S.; Kennedy, G.; Am. J. Sci. 1965, 263, 445-54.
Variables:
Room Temp:
423.15 - 623.15
$\pu{K}$
Pressure:
100 bar - 1400 bar
$\pu{bar}$

Method/Apparatus/Procedure:
The experimental equipment and apparatus are the same as used in previous experimental work [1].
After equilibration, the liquid samples are analyzed for the amounts of $\ce{CO2}$. The composition of the co-existing gas phase was not determined.
The authors also present data for the solubility of $\ce{CO2}$ in aqueous solutions of NaCl.)
Source and Purity of Materials:
- Not stated.
- Not stated.
Estimated Errors:
Ambient temperature: δT/K = ±0.8% (by authors)
Mass concentration (m/v) (1): δS = ±2% (by authors)
