What is the difference between simple distillation and fractional distillation
Answers
Answer:
Simple distillation is the method used to separate substances in mixtures with significantly different boiling points, while fractional distillation is used for mixtures containing chemicals with boiling points close to each other.

Boiling Point
Fractional Distillation: Fractional distillation is used to separate liquids with closer boiling points.
Simple Distillation: Simple distillation is used to separate liquids with boiling point gaps of at least 50 degrees.
Apparatus
Fractional Distillation: Fractional distillation uses a complex apparatus with a fractionating column.
Simple Distillation: A simple apparatus with a flask to contain the mixture, a condenser and a flask to collect purified components is used.
Repetition
Fractional Distillation: The process has to be repeated several times to get the pure components.
Simple Distillation: This is a one run process.
Separation of a Solvent from a Solute
Fractional Distillation: This cannot be used to separate a solvent from a solute.
Simple Distillation: This can be used to separate a solvent from a solute.
Uses
Fractional Distillation: This is used in crude oil refining.
Simple Distillation: This is used to purify sea water.
Conclusion
As explained above, the main difference between fractional and simple distillation is that fractional distillation is used for complex liquid mixtures with closer boiling point. The apparatus and process used for fractional distillation is also complex, unlike simple distillation.
