Variables:
Room Temp:
288.15
$\pu{K}$
Pressure:
2.05 - 2.11
$\pu{kPa}$

Method/Apparatus/Procedure:
All glass apparatus used at very low gas partial pressures, containing a replaceable degassed solvent ampule equipped with a breakable point which could be broken by means of a magnetically activated plunger. Quantity of gas fed into system determined by measuring the pressure change in a known volume. Quantity of liquid measured by weight. Pressure change observed after solvent released. Experimental details described by Rzad and Claes, [1].
Source and Purity of Materials:
- Source not given; minimum purity specified as 99.0 mole%.
- Fluka pure grade; minimum purity specified as 99.0 mole%.
Estimated Errors:
Ambient temperature: δT/K = ±0.05 (estimated by the compiler)
Mass concentration (m/v) (1): δx1/x1 = ±0.01 (estimated by compiler)

(a) Original data at low pressure reported as distribution coefficient; but if Henry's law and ideal gas law apply, distribution coefficient is equivalent to Ostwald coefficient as shown here.
(b) Calculated by compiler for a gas partial pressure of 101.325 kPa assuming that Henry's law and ideal gas law apply.
