Question

Equal amounts or ethanol and water are mixed at room temperature and at 101.3 kPa. Which process is used to separate ethanol from the mixture?

(1) distillation
(2) reduction
(3) filtration
(4) ionization

Answer 1

1) distillation

Answer 2

The answer is (1) distillation. Because the ethanol and water will mix well to form a solution. And the boiling point of ethanol and water are different. Then we can use distillation to separate them.
