Conditions:

Room Temp: 298.1 $\pu{K}$
Pressure: 1.013 bar $\pu{bar}$
Molality (2): m₂/mol kg^-1 = 0.245 - 1.835 mol/kg

Compiler:

P. Scharlin

Methodology:

The apparatus is a combination of previous designs [1,2]. It was modified to achieve a more accurate determination of the volume of the absorbent liquid. The apparatus measures the volume of absorbed gas as the volume of mercury that must be supplied to the system in order to restore the initial pressure.
The raw solubility data obtained are gas/ liquid volume ratios. A detailed description of apparatus, method and procedure is given in [3].

Sample Information:

1. Commercial, purity 99.5 mole%
2. Merck. Grade not given.
3. Distilled and degassed.

Measurement Errors:

Ambient temperature: δT/K = ±0.1
Mass concentration (m/v) (1): δc₁/c₁ < ±1% [estimated by compiler on the basis of the information in Ref. 3]
Pressure: δP/bar = ±0.001
