alleryEthanol–water mixture, on fractional distillation, gives an azeotrope at approximately:
A100% ethanol
B95% ethanol
C68% ethanol
D50% ethanol
Answer & Solution
Correct answer: B. 95% ethanol
Ethanol–water shows large positive deviation
→ **minimum-boiling azeotrope at ~95% ethanol by volume**.
You cannot get pure (100%) ethanol by simple fractional distillation past this point.
