Hello,
I have to write a lab report and there are also some problems to answer.
I cannot find an answer to this one:
Describe a simple method how the composition of the gas phase can be determined.
Hint: Think about how the purity of liquids is usually determined in organic chemistry.
I think the hint refers to the refractive index but I don't know how I can use it to determine the composition.
I know some analytical methods that could be use but they seem to me not simple enough.
PS. It is Physical Chemistry Lab but I think I posted it in a right section, since it is somehow analytical problem.
-
What did the gas phase contain? Was is a simple two component mixture, or something more complicated?
-
It is a general question, it is not really connected to experiment.
I've no clue what should I answer. I can only came up with methods that are too sophisticated.
-
If there is nothing known about the gases present, I don't see how to determine the composition "simply" - whatever it means.

I don't recognize what you mean. Sire, we could use refractive index, in some situations. But determining the purity of a liquid, is that the only way, or best way?
