NEET Chemistry: Separation of Mixtures questions with solutions

Q1. Liquid ethanol can be separated from a mixture of ethanol and water by:

1. Chromatography
2. Fractional distillation
3. centrifugation
4. All of above

Answer: Fractional distillation

Ethanol and water are miscible liquids with different boiling points, so they are best separated by fractional distillation. Chromatography and centrifugation are not appropriate for separating two mixed liquids like this.
