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:
(1)VEB Leuna Works; 99.8 vol %; the impurity was mostly water (author).
(2) DDR pro analysis grade by DDR Standard TGL 5021.
(3) Double distilled.
Estimated Errors:
Temperature: Not given.
