Solubility of gases in liquids. 17. The solubility of He, Ne, Ar, Kr, H/sub 2/, N/sub 2/, O/sub 2/, CO, CH/sub 4/, CF/sub 4/, and SF/sub 6/ in tetrachloromethane at 283-318 K
The Ostwald coefficients L/sub 2,1/(T,P) of He, Ne, Ar, Kr, H/sub 2/, N/sub 2/, O/sub 2/, CO, CH/sub 4/, CF/sub 4/ and SF/sub 6/ in tetrachloromethane have been determined at about atmospheric pressure, and from 283 to 318 K, by a modified Ben-Naim/Baer apparatus. Both pressure control and measurement of the volume of gas dissolved in a given amount of solvent were effect by a microprocessor. This improved, medium-precision design (about +.1%) combines easy handling with automated data retrieval, and is totally mercury-free. Test measurements for N/sub 2/, O/sub 2/, CO/sub 2/, and CH/sub 4/ dissolved in pure water showed excellent agreement with recent high-precision results. Henry coefficients H/sub 2,1//(T,P)/sub s,1/ are evaluated from the solubility data. Their variations with temperature yield the enthalpy changes upon solution ..delta..H/sub 2//sup 0/, which are compared with recent calorimetric measurements. Results obtained through application of scaled particle theory are also given.
