298.15	1.421	+ Sodium Chloride	0.887	+ Nitric Acid	0.0722	*	2.308	*

Notes:
   ^*  quoted in original paper.
   ⁺  Calculated from ionic strength and statement in paper that ratio of ionic strength of sodium chloride to total ionic strength was 1:0.6156.

Method/Apparatus/Procedure:
   Concentrated solution prepared by weighing, 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 99.6 mole per cent.
   2. Analytical grade sample.
   3. Analytical grade sample.
   4. No information given.

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