SDS Volume

Volume 62. Carbon Dioxide in Water and Aqueous Electrolyte Solutions, p None

Source Publication

Yasunishi, A.; Yoshida, F.; J. Chem. Eng. Data 1979, 24, 11-14.

Conditions:

Room Temp: 288.15 - 308.15 $\pu{K}$
Pressure: 101.325 $\pu{kPa}$
Amount concentration (2): C₂/mol L^-1 = 0 - 5.096 g/L

Compiler:

C.L. Young

Methodology:

Volumetric apparatus with multibulb buret and magnetic stirrer. Amount of solution and gas absorbed determined volumetrically. Density and composition of solution determined after absorption. Details in [1].

Sample Information:

High purity grade sample, purity 99.96 mole%.
(2,3) Guaranteed reagent, solution degassed by boiling.

Measurement Errors:

Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δL = ±1%
