Method/Apparatus/Procedure:
Volumetric apparatus with multibulb buret and magnetic stirrer. Amount of solution and gas absorbed determined volumetrically. Density and composition of solution determined after absorption. Details in [1].
Source and Purity of Materials:
- High purity grade sample, purity 99.96 mole%.
- (2,3) Guaranteed reagent, solution degassed by boiling.
Estimated Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δL = ±1%
