Answer

Simple distillation is a process that is used for separating two miscible liquids that there boiling points are different by less than 25 K.
In this process, there is a fractionating column.
For example, the separation of different gases from the air, different factions of petroleum products, etc

Answer

Fractional distillation is the method used for the separation of components of a mixture containing two miscible liquids that boil without decomposition and have sufficient difference in their boiling points.

Two conditions essential for using this method are:

1) Two liquids must be miscible that is they totally mix with each other.

2) The difference between the boiling points of the liquids should be greater than 25K.

Answer

This is because when two miscible liquids are heated
1. they can't decompose
2. if they have a boiling point difference of more than 25 degrees (in any scale), the more volatile component evaporates first and passes through the condenser and after getting liquefied it gets collected in a beaker
while the other component remains in the original beaker

Answer

If boiling points will not have the sufficient difference then both the liquids may turn into vapours and there will be no separation of liquids .. in this case fractional distillation is used

The Basic Principle behind Simple Distillation Process

The basic principle behind the simple distillation process is to separate two or more miscible liquids based on their differences in boiling points. This process is commonly used in various industries and laboratories to obtain purified liquids or to separate a desired component from a mixture of liquids.

Sufficient Difference in Boiling Points
The first requirement for simple distillation is that there should be a sufficient difference in the boiling points of the two miscible liquids. The boiling point of a liquid is the temperature at which its vapor pressure is equal to the atmospheric pressure. If the boiling points of the liquids are too close, it becomes difficult to separate them effectively using simple distillation.

Liquids Boil Without Decomposition
Another important factor is that the two liquids should boil without decomposition. During distillation, the liquid is heated to its boiling point, and if the liquid decomposes before reaching its boiling point, it will not be possible to separate the components effectively.

The Process of Simple Distillation
1. Heating: The mixture of liquids is placed in a distillation flask and heated. The liquid with the lower boiling point will start to vaporize first.

2. Condensation: As the vapor rises, it enters a condenser, which is a coiled tube or a similar apparatus. The condenser is cooled using cold water or another cooling medium, causing the vapor to condense back into liquid form.

3. Collection: The condensed liquid is collected in a separate container known as the receiver. The liquid collected in the receiver will have a higher concentration of the component with the lower boiling point.

4. Separation: The process of heating, vaporization, condensation, and collection continues until most of the liquid with the lower boiling point has been separated from the mixture. The remaining liquid in the distillation flask will have a higher concentration of the component with the higher boiling point.

Conclusion
In conclusion, the basic principle behind the simple distillation process is the difference in boiling points of two miscible liquids. By heating the mixture and condensing the vapor, the liquids can be effectively separated based on their boiling points. Simple distillation is a widely used technique in various industries and laboratories to obtain purified liquids or separate desired components from mixtures.
