Notes:
   a  γ2 = mass concentration of ferric hydroxide
   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 to give higher pressures. Concentration of ferrous hydroxide determined by precipitation with ammonium sulfate.

Source and Purity of Materials:
   (1) Purity 99.42 mole %.
   (2) Ferric hydroxide solution was prepared by the method of Noyes (Ref. 2). And dialysed.
   (3) Nothing specified.

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