Explain what is the difference between fractionation and distillation?
Answers
Explanation:
Both methods are used to separate the components present in the solution based on the melting points
Distillation :- This technique is used when the boiling point of chemicals are different in the mixtures
Fractionation :- This technique is used when the boiling point of chemicals are close to each other in the mixtures

Answer:
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.
