Methodology:
The apparatus consists of a gas buret, a solvent reservoir, and an absorption pipet. The volume of the pipet is determined at various meniscus heights by weighing a quantity of water. The meniscus height is read with a cathetometer.
The dry gas is introduced into the degassed solvent. The gas and solvent are mixed with a magnetic stirrer until saturation. Care is taken to prevent solvent vapor from mixing with the solute gas in the gas buret. The volume of gas is determined from the gas buret readings, the volume of solvent is determined from the meniscus height in the absorption pipet.
Sample Information:
- Ethene. Prepared by dropping ethanol into orthophosphoric acid. The gas was cooled, passed through several wash solutions, dried, and fractionated from liquid air several times.
- Acetone. Nippon Pure Chemical Co. or Merck. Extra pure grade. Recrystallized with sodium sulfite and stored over calcium chloride. Fractionated, BP (760 mmHg) = 56.09°C.
Measurement Errors:
Ambient temperature: δT/K = ±0.05
Mass concentration (m/v) (1): δx1/x1 = ±0.01
System Components:
- Ethene, $\ce{ C2H4 }$; [74-85-1] NIST WebBook
- Acetone, $\ce{ C3H6O }$; [67-64-1] NIST WebBook
Experimental Data
The mole fraction and the Bunsen coefficient values were calculated by the compiler with the assumption the gas is ideal and that Henry's law is obeyed.
Smoothed Data: For use between 273.15 K and 313.15 K.
