Volume 62. Carbon Dioxide in Water and Aqueous Electrolyte Solutions, p None
Original Measurements
Mackenzie, J. J.; Ann. Phys. (Leipzig) [3] 1877, 1, 438-51.
Variables:
Room Temp:
281.2 - 303.2
$\pu{K}$
Pressure:
94.45 - 100.2
$\pu{kPa}$
Prepared by:
Method/Apparatus/Procedure:
The apparatus consisted of a bulb of known volume in which the initial pressure and carbon dioxide (reduced to 0 °C) was measured; a bulb of known volume for the solvent; and a manometer system to adjust the final volume of the unabsorbed wet gas and measure its total pressure (reduced to 0 °C). . The final total pressure of wet gas was reduced to the partial pressure of carbon dioxide by subtraction of the solution water vapor pressure.
There was a statement that the carbon dioxide solubility in water was measured, but no solubility values were given.
Source and Purity of Materials:
- Carbon dioxide. Prepared by action of sulfuric acid on marble. Dried by bubbling through sulfuric acid.
- Salts. Recrystallized. Solution prepared by weight and checked by evaporation to dry salt.
- Water. Nothing specified.
Estimated Errors:
Ambient temperature: Nothing specified.
Mass concentration (m/v) (1): Nothing specified, but see standard deviations in table.
Components:
- Carbon dioxide, $\ce{ CO2 }$; [124-38-9] NIST WebBook
- Chloride salts (x3),
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The compiler calculated and added the Kelvin temperatures, the concentration and molality values and the standard deviations.
These data are of marginal value. Some show a standard deviation as large as 6.6 %, although many show a standard deviation under 3 %.
See the ammonium chloride, sodium chloride, and potassium chloride data sheet from this paper for additional comments.
