Notes:
   ^a  Calculated by the compiler.
   ^b  The authors measured and corrected for the density of the pure CO₂ gas at the same temperature and pressure.
   ^c  Solubility as volume of gas reduced at STP per volume of water. (At the equilibrium pressure of the measurement and the real volume of gas.)

Method/Apparatus/Procedure:
   An all-glass apparatus was used. It was not stated if stirring was used. Thermostatted at ± 0.1°C. The dissolved gas was measured as a pressure difference in a known volume.

Source and Purity of Materials:
   (1) From marble. Dried and air free.
   (2) Distilled, degassed.

Estimated Errors:
   Solubility: δS = ± 3% (by compiler)
   Temperature: δT/K = ± 0.1 (by authors)
