Notes:
   ^a  Calculated by the compiler.
   ^b  Solubility expressed as cm³ of gas at STP dissolved by 1 cm³ of solution at the temperature of the experiment and at a partial pressure of gas of 1 atm.

Method/Apparatus/Procedure:
   An all glass apparatus was used. The gas was bubbled through water kept in a constant temperature bath until equilibrium was reached.
After equilibration a liquid sample was volumetrically analyzed for its CO₂ content.
The volume of the solution was pycnometrically determined at the temperature of the measurement.
