Separation of a mixture of two gases by absorption in the liquid solvent depends upon the difference in their____________________?
Correct answer: B. Solubility
- A. Viscosity
- B. Solubility
- C. Density
- D. Relative volatility
Explanation
Selective absorption separates gases according to how readily each dissolves in the solvent, that is, according to their relative solubilities. Viscosity and density affect hydraulics, while relative volatility belongs mainly to distillation.
