Liquid ethanol can be separated from a mixture of ethanol and water by:
Liquid ethanol can be separated from a mixture of ethanol and water by:
- A. Chromatography
- B. Fractional distillation
- C. centrifugation
- D. All of above
Step-by-step solution
Ethanol and water form a miscible mixture. Fractional distillation exploits their different boiling points to separate them, though an azeotrope limits purity. Chromatography is unsuitable for bulk liquid separation, and centrifugation cannot separate miscible liquids. Thus only fractional distillation works.
