Original Measurements
Gerecke, J.; Diss. Dr. rer. Nat. 1969, Hochsch. "Carl Schorlemmer", Leuna-Merseburg, DDR.
Variables:
Ambient temperature: 288.15 - 333.15 K
Pressure: 101.325 kPa
Amount concentration (2): C2/mol dm-3 = 0 - 2
Prepared by:
Method/Apparatus/Procedure:
The principle of the Ostwald method was used in which a measured volume of gas-free liquid is stirred in the presence of the gas, and its decrease in volume is measured in a burette over mercury. The volume of liquid was measured at the experimental temperature. For calculation of the Kuenen coefficient, the density of the solution was obtained from Landolt-Börnstein extant 1969. The molar concentration of salt in the liquid was standardized at 20°C. These data are analyzed and discussed further in Ref. 1.
Source and Purity of Materials:
- VEB Leuna Works; 99.8 vol%; the impurity was mostly water (author).
- DDR pro analysis grade by DDR Standard TGL 5021.
- Double distilled.
Estimated Errors:
Ambient temperature: Not given.
