Original Measurements

Yasunishi, A.; Tsuji, M.; Sada, E.; Adv. Chem. Ser. 1979, 177, 189-203.

Variables:

Room Temp: 298.15 $\pu{K}$
Pressure: 101.325 $\pu{kPa}$
Amount concentration (2): (C₂ + C₃)/mol dm^-3 = 0 - 2.873 mol/L

Prepared by:

C.L. Young

Method/Apparatus/Procedure:

Volumetric apparatus with multibulb buret and magnetic stirrer. Amount of solution and gas absorbed determined volumetrically. Partial pressure determined from total pressure and vapor pressure of solution. The vapor pressure of the mixed salt solution estimated by the method of Robinson and Bower [1] from corresponding data for each component salt solution. Apparatus similar to that described in [2].

Source and Purity of Materials:

1. Extra pure grade, purity 99.96 mole%.
2. (2,3) Reagent grade.
3. Deionized.

Estimated Errors:

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