Conditions:

Room Temp: 298.15 $\pu{K}$
Pressure: 101.325 $\pu{kPa}$
mole frac. 2 (l) : 10²x₂ = 0 - 29.15

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 supersaturation.

Sample Information:

1. Commercial cylinder, 99.8% pure.

3. Distilled.

Measurement Errors:

Ambient temperature: δT/K = ±0.03 (authors)
Mass concentration (m/v) (1): δα/α, δS/S = ±0.002 (authors)
