Method/Apparatus/Procedure:
Solutions made up by weight and density measured but not reported in paper. Equilibrium established between a measured volume of gas and a measured amount of gas-free liquid in a cell fitted with a magnetic stirrer. Amount of gas absorbed estimated from change in volume of gas. Details in source.
Source and Purity of Materials:
(1) Commercial sample, minimum purity 99.8 mole %.
(2) Analytical grade.
(3) Distilled and degassed.
Estimated Errors:
Solubility: δα = ± 2 % (estimated by the compiler)
Temperature: δ
