Notes:
   ^a  Calculated from ionic strength and statement in paper that ratio of ionic strength of calcium chloride to ammonium nitrate was 1:1.
   ^b  Quoted in original paper.
I = ionic strength; α = Bunsen coefficient [cm³ (STP) cm^-3 atm^-1].

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.
   (3) No details given.

Estimated Errors:
   Solubility: δα = ± 2 % (estimated by the compiler)
   Temperature: δT/K = ± 0.2 (estimated by the compiler)
