Notes:
   a  Added by the compiler.
   b  α = Bunsen coefficient [cm3 (STP) cm-3 atm-1].
   c  Average of five determinations. Standard deviation sα = 0.005.

Method/Apparatus/Procedure:
   Volumetric method. The apparatus is described in detail in the source. The CO2 was purified in the line and sublimed into the system. Mercury levels were read with a cathetometer to ± 0.05 mm. Atmospheric pressures were read to ± 0.1 mm with a mercury barometer and were corrected to 0 °C. The volumes determined were reproducible to ± 0.02 mL.

Source and Purity of Materials:
   (1) Commercial. Purity 99.9 %.
   (2,3) Fisher Certified Reagents. Purity better than 99.3 %.
   (4) Purified. Source not specified.
(5) Conductivity water, distilled from a quartz still. Conductivity less than 1 x 10-7 Ω-1 m-1.

Estimated Errors:
   Solubility: δα = ± 1.1 % (authors)
   Temperature: δT/K = ± 0.05 (authors)
