A mixture of water and ethanol can be separated using 

A. crystallization

B. sublimation

C. decantation

D. distillation

The correct answer is D. Distillation ✅

Explanation:

Water and ethanol form a miscible mixture (they mix completely).
To separate miscible liquids, we use distillation, which works based on difference in boiling points.

• Ethanol boils at about 78 °C

• Water boils at 100 °C

When heated:

• Ethanol vaporizes first

• The vapor is cooled and condensed back to liquid → collected separately

Why others are wrong:

• Crystallization → used for solids from solutions

• Sublimation → used for solids that change directly to gas

• Decantation → used for immiscible liquids or solid–liquid mixtures

👉 Final Answer: D. Distillation
