Steam distillation is used for separation of high boiling ____________________?
Correct answer: C. Both A. and B.
- A. Substances from non-volatile impurities
- B. Volatile impurity from still higher boiling substances
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Steam distillation allows a high-boiling, steam-volatile substance to distil below its normal boiling point, separating it from nonvolatile or still higher-boiling material. Hence both listed applications are valid.
