Methodology:
The prepared solvent and solution were charged into an evacuated cell after degassing, and the mass of solvent was determined by weight. Gas was introduced into the cell from a measuring buret in which the gas was stored over mercury. The cell was agitated while the gas pressure was maintained by adjusting the gas volume. The Ostwald coefficient was determined from the mass of solvent and the volume of gas absorbed. Solubilities were measured at pressures above and below atmospheric.

System Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Teepol CH 53, [50642-03-0] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Note: Teepol CH 53 is sodium salt of dodecyl benzenesulfonic acid mixture with α-(nonylphenyl)-w-hydroxypoly(oxo-1,2-ethanediyl).
The small amount of the surface active agent does not affect the solubility of carbon dioxide in water although it decreases the water surface tension to about one-half the pure water value.

(a) Calculated by the compiler.
(b) σ is surface tension.
In the original paper σ was given in units dyn cm-1.
Relation to SI units: 1 dyn cm-1 = 10-3 N m-1 = 10-3 J m-2.
(c) Ostwald coefficient
(d) Solvent pure water
(e) Solvent pure water + 1 % Teepol CH 53.
