What substance is removed at the filtration stage during the fractional distillation of air?
First the components or the gases in the air are liquefied(made into liquid)under low temperature and high pressure.Then it is passed through the fractionating column.Gases evaporate there.Then the gases can be obtained.
What is the reason of using beads in the distillation flask when distilling water?
If you put boiling beads in a solution, then it is easier to observe whether the solution begins to boil because the beads will vibrate. During the distillation process it is difficult to distinguish which solution is boiling so that's why they use boiling beads (quite honestly, it doesn't matter to me because I still don't see the difference!)
Why are boiling chips placed in distilling flask during distillation?
They provide a site for nucleation and prevent the liquid from superheating.
Which processes occur during distillation?
condensation
What process occurs during distillation?
condensation then evaporation
The boiling point of both the liquids should be known during separation by fractional distillation method.why?
Separation by distillation is based on the differences between boiling points.
What is to purify by boiling and condensing?
This is known as a distillation. Ethanol and water can be separated using this process because their boiling points are different which allows them to be "boiled off" at different temperatures.
What is boiling point in science?
during boiling,the temperature of a mixture is different at different times. during boiling,the temperature of a substance changes at the start then it becomes the same and constant.
What would be the effect on the boiling point of ethyl alcohol if the pressure were reduced during the distillation process?
It would decrease
Is there two changes of state in distillation?
The changes of state that happen during distillation are: Liquid to a gas and gas to a liquid
How it is possible Diethylene glycol boiling point is 245 while its auto ignition temp is 225 deg and how it is safe during its distillation as its auto ignition temp is lower than its boiling?
yes its possible
How can you overcome the problem of decomposition of certain organic liquid during distillation process?
you can over come the problem of decomposition of certain organic liquid by rarefaction atmospheric pressure that the boiling point of liquid become less than of its previous that prevent decompose it before its boiling.

What does evaporation have in common to fractional distillation?
During distillation liquids are evaporated.
How is fractional distillation used during the making of whiskey?
Distillation is used to extract ethanol.
What is the function of boiling chips in the esterification reaction?
most of the carboxylic acids used during esterification are very volatile. boiling chips are added to maintain a smooth heating of the mixture and to prevent a voilent heating.
