SDS Volume (2796)
Volume 62. Carbon Dioxide in Water and Aqueous Electrolyte Solutions, p None
Original Measurements
Postigo, M. A.; Katz, M.; J. Solution Chem. 1987, 16, 1015-24.
Variables:
Room Temp:
288.15 - 308.15
$\pu{K}$
Pressure:
101.3
$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
Known volumes of gas and solvent were introduced into 250 mL flask, then initial and final pressures were measured by a transducer connected to a digital multimeter. The flask was submerged in a thermostatic bath. Full details given in [1].
Source and Purity of Materials:
- Carbon dioxide: no information
- Water: degassed by boiling; composition checked by refractive index measurement at 298 K.
Estimated Errors:
Ambient temperature: δT/K = ±0.02
Mass concentration (m/v) (1): δL/L = 1%
Pressure: δP1/Pa = ±10
