Why can 2 liquids have same boiling points but be different liquids?

The answer is simple: it is easy to separe liquids with very different boiling points.

∙ 12y agoBecause you are not able to see the difference. With both having the same boiling point, standard separation tests would fail. If you want to separate two liquids all you have to do is turn one of the two into a solid or gas.
Wiki User
∙ 13y agoThey can be separated by the process called fractional distillation.
Wiki User
∙ 12y agoNope. If the two liquids are mixed together you can't separate those two because you wouldn't know which is which.
Wiki User
∙ 11y agoBoiling point is just one property. There are many other properties that could vary between the two liquids.

What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
How can separate 2 mixed liquids from each other?
In most cases, two mixed liquids can best be separated by the process of distillation, in which the liquid with the lower boiling point is boiled off and collected as vapor, and it can then condense back into a liquid. It is also possible to separate two mixed liquids by cooling them to the point that one of the liquids freezes; no two liquids would have exactly the same freezing point, just as they do not have exactly the same boiling point (of course, if the freezing points or the boiling points are very close, that makes the separation process harder).
When the liquid as a constant boiling point is it pure or not pure?
All pure liquids, such as water, H20, have constant boiling points at certain atmospheric pressures, which is helpful in determining the identity of an unknown liquid. Some liquids have constant boiling points that are not pure, such as nail polish remover, or ethyl acetate. Since it is a mixture of more than one pure liquid, it is not a pure liquid itself, but if always mixed in the same ratios, will have a constant boiling point.
As the molecular mass of a nonpolar liquids increase the boiling points does what?
If the mass increases with the volume (ie if the density remains the same) then the boiling point remains constant. If the volume remains contstant with rising mass (ie greater density) then the boiling point increases.
What are the two miscible liquids having same boiling point?
You are asking for two liquids that share the same boiling point and dissolve in each other? The best I could find so far are allyl alcohol (97.2 C) and propyl alcohol (97.5 C). There are probably other liquids (especially organic) out there that share closer boiling points. I also found that the elements erbium (atomic number 68) and terbium (atomic number 65) share the same boiling point--3230 C. They may or may not be miscible. I guess it's hard to tell at that temperature.
Do all liquids have the same boiling and melting point?
No. The melting and boiling points of liquids vary considerably.
Do the different liquid have different boiling points?
Boiling point is the temperature at which the atmospheric temperature becomes equal to temperature of the liquid......hence it completly depends upon the atmospheric temperature and the temperature of the liquid.....so different liquids will have different boiling points......
How does distillation separate a mixture of differant liquids?
We can separate a mixture of different liquids in the process of distillation by evaporating and condensing to make sure nothing is dissolved in it. Distillation as a separation method is based on the differences between boiling points of liquids.
Why elements of the same shape have different boiling points?
elements of same shape have different boiling points because their bonding may vary! the elements with covalent bonds will have high boiling point!
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
The laboratory process of distillation does not involve?
liquids with the same boiling points. because they would evaporate at the same time leaving you without a solution.
What is the boiling point of glue?
Different glues have different boiling points
Are boiling points of all liquids the same?
All liquids have different boiling point (BP). It's one of the must important characteristics of liquids. You can distinguish and also separate a mixture of liquids by boiling off one with a lower BP. The BP of every liquid depends upon the attractive forces among the atoms or molecules of the material such as hydrogen bonds, dipole attraction, London forces, etc....

Why do all liquids NOT evaporate at the same time?
Because all liquids have different boiling points. For instance: the boiling point of ethyl alcohol (the kind you drink) is 172.4 oF, while that of methyl alcohol (the kind that will kill you or make you blind if you drink it) is 151 oF, and isopropyl alcohol (the kind you use for a massage) is 177 oF. The boiling point of glycerine is 554 oF, while that of hydrogen is -423 oF.
Do all liquids evaporate and solidify at the same temperature?
No. All liquids have different specific freezing points. Some liquids may have the same point, but that doesnt change anything.
