Separation of two volatile liquids by distillation makes use of their________________________?
Correct answer: A. Relative volatility
- A. Relative volatility
- B. Selectivity
- C. Solubility
- D. Density difference
Explanation
Distillation separates volatile liquids because the more volatile component preferentially enters the vapour phase. This separation tendency is measured by relative volatility, whereas solubility and density difference are not the governing equilibrium basis.
