Why is better separation of two liquids achieved by slow rather than fast distillation?

because faster distillation usually means higher temperature. Under the circumstances, the mixture often evaporates too quickly for the two liquids to separate properly.
Also, distillation work on the principle of different boiling points for two liquids, if you distillate too quickly, its easy to overrun the first boiling point and get a bunch of unwanted impurities.

∙ 13y agoin faster distillation the end product is more likely to have impurities, because the gaseous material flows faster into the condenser and it more likely to carry over impurities.

What is the advantage of simple distillation to fractional distillation?
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
What is the function of the fractionating column in fractional distillation?
The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled. The reason that fractional distillation gives better separation between the liquids is because the glass beads in the fractionating column provide "theoretical plates" on which the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the compound over and over. The more volatile liquids will tend to push towards the top of the fractionating column, while lower boiling liquids will stay towards the bottom, giving a better separation between the liquids.
Explain why a distillation would not separate a mixture of the miscible liquids formic acid which boils at 100.7 degrees celsius and water which boils at 100 degrees celsius?
This is because their boiling points are close. Distillation is used to separate mixtures in which their constituents have boiling points that are relatively far apart. A better method would be fractional distillation which can be used to separate mixtures in which their constituents have relatively close boiling points.

What is a distillation disadvantage of fractional distillation?
One of the main sources of all types of energy is from sun.. The sources like fossil fuels, etc r gonna sure disappear some years later.. also its utilisation now also creates serious impact on life of human beings...u can c in many places were its temperature is hike... so installation of other devices for purification s a hard tiring process. so the better option s to use the available source for the purification process will be a good one. so its a advantage...

Is the separation of an organic liquid by distillation better or worse if salt is present?
This is not important if the salt is not soluble in a component.

Why are packed and spinning band fractional distillation columns more efficient than unpacked columns?
A packed fractional distillation column will be more effective at separating two closely boiling liquids than an empty one because you have more surfaces for condensation and revaporization of the liquid. A packed fractional distillation column has many more surfaces two allow the mixture of vapors to condense and distill again over and over to effectively separate.

What is the difference between simple distillation and fractional distillation?
Simple distillation refers to the "simple" separation of a solid and a liquid by evaporating the liquid and collecting it after it passes through a condenser to be changed into a liquid state. Fractional distillation refers to the more complex way of separation, usually involving a liquid/liquid mixture (eg. ethanol and water). these can be separated since they both have different boiling points. When this mixture is heated the ethanol having the lowest boiling point boils off first, followed by the water. However the fractional coulomb condenses both gases back into liquid, and fall back in the flask, with time the ethanol gains enough energy to over come the fractional coulomb (this happen before the water does this since ethanol has a LOWER boiling point) and pass through the condenser, changes into a liquid and is collected.
Distillation is a way to separate a mixture using the physical property of boiling point.?
Distillation would be one because if you boil the mixture of the two liquids, one of the substance will boil first and therefore you will collect its vapour first, than you can condense it. However this method works better with two mixture with two very different boiling point.
Why are liquids better than gases?
Liquids are not better than gases; this depends only on the desired applications.
Why is that slow distillation better than fast distillation?
In order to prevent entrainment or liquid carryover, distillation must be slow. If it is heated vigorously, it will result in loss of products and carry over of other components as liquid.
