Method/Apparatus/Procedure:
Concentrated solutions prepared by weighting, less concentrated solutions prepared by dilution. 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 and Ref. 1.
Source and Purity of Materials:
(1) Commercial sample, purity 99.8 mole %.
(2) Analytical grade sample.
(4) No details given.
Estimated Errors:
Solubility: δα = ± 2 % (estimated by the compiler)
Temperature: δ
