Volume 62. Carbon Dioxide in Water and Aqueous Electrolyte Solutions, p None
Original Measurements
Bartels, H; Wrbitzky, R.; Pflügers Arch. 1960, 271, 162-8.
Variables:
Room Temp:
288.15 - 311.15
$\pu{K}$
Pressure:
"atmospheric"
$\pu{atm}$
Prepared by:
Method/Apparatus/Procedure:
Water was saturated with $\ce{CO2}$ in rotating tonometer. The technique is described in [1].
The $\ce{CO2}$ contents of the equilibrated solutions was determined in the manometric gas apparatus [2].
Source and Purity of Materials:
- From cylinder; purity 99.8%.
- Distilled.
Estimated Errors:
Ambient temperature: δT/K = ±0.1
Mass concentration (m/v) (1): 0.004 < absolute value of δα/α < 0.02
