Original Measurements
Findlay, A.; Creighton, H. J. M.; J. Chem. Soc. 1910, 97, 536-61.
Variables:
Room Temp:
298.15
$\pu{K}$
Pressure:
100.5 - 170.8
$\pu{kPa}$
Mass density:
102γ2/g cm-3 = 0.392 - 2.289
g/mL
Prepared by:
Method/Apparatus/Procedure:
Gas burette and absorption pipette similar to that of Geffcken [1] except that the manometer tube was longer. Concentration of $\ce{As2S3}$ determined by precipitation with hydrochloric acid, drying at 80 °C and weighing.
Source and Purity of Materials:
- Purity 99.42 mole%.
- Prepared by passing hydrogen sulfide into arsenic trioxide solution. Hydrogen bubbled through colloidal solution, filtered and partially degassed.
- Nothing specified.
Estimated Errors:
Ambient temperature: δT/K = ±0.1
Mass concentration (m/v) (1): δS = ±0.25%
