Fractional Distillation
1. What is Fractional Distillation?
Fractional Distillation is process of separating two or more miscible liquids at different boiling temperature.
2. How can you Separate two liquids that have less than 25 K difference in Boiling Points?
We can separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K by fractional distillation.
3. How will you separate a mixture of Oil and Water?
To separate a mixture of oil and water, we need a separating funnel as both are immiscible liquids. Pour the mixture in separating funnel and let the funnel stand undisturbed for sometime. So that separate layer of oil and water are formed. Open the stopcock of the separating funnel and pour out the lower layer of water carefully.
4. Can we separate Alcohol dissolved in Water by using a Separating Funnel?
No, being miscible they cannot be separated by using a separating funnel.
5. What is the difference between Separating Funnel and Fractional Distillation?
Separating Funnel
Fractional Distillation
Separating funnel is used to separate two immiscible liquids. Fractional distillation is used to separate two miscible liquids. Fractional distillation separates two miscible liquids based on their boiling point. Separating funnel separates two liquids of different density. Example: Water and Alcohol. Example: Oil and Water.
6. Which liquids are separated using the Fractional Distillation method?
Liquids with identical boiling points are separated using the fractional distillation method.
7. What steps are involved in the Fractional distillation method?
Steps involved in the Fractional distillation method are:
- Evaporation
- Condensation
- Collection
8. What are the essential conditions for Fractional Distillation?
Eritical conditions for fractional distillation are:
- Liquids must be miscible with each other.
- Boiling points of the two liquids must have a difference of fewer than 25 degrees Celsius.
Fractional Distillation
Fractional Distillation is a technique used in the separation of miscible liquids. The process requires repeated distillations and condensations of the mixture. The separation of the mixture happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize and are collected separately. Fraction Distillation works on the liquid that has liquid mixed together with different heat of vaporization. Petroleum Oil is distilled into Petrol, Diesel, Petroleum Jelly, etc. using the Fractional Distillation method.
In this article, we will learn about fractional distillation in chemistry, the fractional distillation definition, the fractional distillation process, and others in detail.
