Fractional distillation of a fermented ethanol and water mixture stops at roughly what ethanol content by volume?
A68%
B100%
C95%
D50%
Answer & Solution
Correct answer: C. 95%
Ethanol and water form a minimum boiling azeotrope at about 95 percent ethanol by volume, beyond which no further separation occurs.
