Notes:
   a  γ2 = mass concentration of arsenic trisulfide
   b  S = concentration of gas in liquid phase/concentration of gas in gaseous phase


Method/Apparatus/Procedure:
   Gas burette and absorption pipette similar to that of Geffcken (Ref. 1) except that the manometer tube was longer. Concentration of As2S3 determined by precipitation with hydrochloric acid, drying at 80 °C and weighing.

Source and Purity of Materials:
   (1) Purity 99.42 mole %.
   (2) Prepared by passing hydrogen sulfide into arsenic trioxide solution. Hydrogen bubbled through colloidal solution, filtered and partially degassed.
   (3) Nothing specified.

Estimated Errors:
   Solubility: δS = ± 0.25 %
   Temperature: δT/K = ± 0.1
