Conditions:

Room Temp: 273.35 - 313.15 $\pu{K}$
Pressure: 101.325 $\pu{kPa}$
Molality (2): m₂/mol kg^-1 = 0 - 3 mol/kg

Methodology:

The principle of the Ostwald method was used in which the gas is agitated with a measured quantity of gas-free liquid and the decrease in volume of solution-saturated gas is measured in a burette over mercury. The pressure was adjusted to yield one atmosphere partial pressure of carbon dioxide. The volume of gas was reduced to 0 °C by the ideal gas law. Experiments were conducted to show that the agitation did not cause super-saturation.

Sample Information:

Measurement Errors:

Ambient temperature: δT/K = < ±0.1 at 0.2°C, ±0.03 at other temperatures (authors)
Mass concentration (m/v) (1): δα/α, δS/S = ±0.002 (authors)
