What is it called when you separate liquids by boiling and condensing them at different temperatures?
Fractionation. One other specialized application is called distillation. I'd put it differently. Distillation refers to any boil and condense process. Alcoholic spirits are distilled and in many cases the idea is not to separate the components too much. Simple distillation does separate liquids at different temperatures though you would not normally refer to it as fractionation. To do fractionation effectively the cycle must be repeated many times, which can be done automatically with a fractionating column. The components that emerge in succession are called fractions.
What effect does the condensation have on distillation when liquid is runnung from the bottom of the distillation column back into the distillation flask?
returning condensate is rich in high boiling point allowing lower boiling point substance to distill over.
How separate methylated spirits from water?
Methylated spirits are also called denatured alcohol. They are a mixture of ethanol and methanol intended for industrial use, and are meant?æto be foul smelling or tasting in order to discourage abuse.
Why ethyl alcohol and water cannot be separated into pure components by fractional distillation?
Due to an effect called the aziotropic effect. Some of the water remains bound to the ethanol raising the BP and getting dragged over with it. The same thing happens with sugars from a wash. Further to this, ethanol is hygroscopic so it will absorb water from the atmosphere when exposed. The best you can do is between 90 - 98% ethanol.
How could you separate a mixture of rubbing alcohol and water?
To separate these, use distillation. Heat up the solution, and the alcohol will rise. Collect the water, and then the alcohol at the other end of the equipment! The simplest and most common way of separating water and alcohol is through distillation. Multiple distillations can be conducted to obtain a high percentage of alcohol, but will eventually form an azeotropic mixture, which can be separated no further through simple distillations. By distillation, alcohol boils at a lower temperature(78.1*C) vs. (100*C)for water. By heating it to its boil point you would turn into vapor. With the right equipment you can channel this vapor to another container where can cool and condense back into a liquid, leaving behind only water.
In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
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.
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.
Reasons why distillation may not have been a benefit to humans?
Fractional distillation of crude oil has increased its use by humans. This has lead to increased pollution. Over reliance on a non-renewable resource that may eventually lead to a massive economic collapse/war/etc.
Can steam distillation be done using a mixture of ethanol and water why and why not?
I hesitate to say that it literally can't be done, but ethanol dissolves things that water doesn't and the whole point of steam distillation is that the thing you're steam distilling needs to not be very soluble in water, so at best there's no real benefit from adding ethanol and at worst you can't separate your desired product out of the ethanol/water mix.If you're not trying to separate it out, then ... you're not really doing a "steam distillation", you're doing an extraction. Gin, for example, is made by allowing the vapors from an ordinary distillation of ethanol/water (to increase ethanol content) to pass over/through substances like juniper berries to pick up some of the essential oils from these and give the resultant product flavor.
What is the fractional part 1 over 6 of 60?
The fractional part is 0 since 1 over 6 of 60 is an integer.
Distillation set up?
A distillation set up involves a boiling flask over a Bunson burner. This is connected to a distillation tube the flows into a beaker.
What would the fractional Notation be of 44 and 7 over 8 percent?
What would the fractional Notation be of 44 and 7 over 8 percent?
What is fractional notation for 2?
Any whole number in fractional notation is itself over 1. so, 2 in fractional notation is 2/1. Simple!
Why is PC preferred over laptop?
if you mean why is a desktop preferred over a laptop. then i would answer that they aren't and that laptops are preferred because of their convenience

3 over 8 plus -1 over 8 in fractional form?
3 over 8 plus -1 over 8 in fractional form is 2 over 8, or 2/8, and can be reduced to 1 over 4, or 1/4.
