Notes:
   ^a  Calculated by the compiler.
   ^b  Bunsen coefficient [cm³ (STP) cm^-3 atm^-1].

Method/Apparatus/Procedure:
   All-glass apparatus. The total pressure was kept constant during equilibration. The equilibration cell was shaken in a constant temperature bath. After equilibration, a liquid sample was volumetrically analyzed for water and CO₂ content.

Source and Purity of Materials:
   (1) "Pure". Saturated with water vapor.
   (2) Distilled.

Estimated Errors:
   Solubility: δα = ± 0.005 (by author)
