Is it possible to take pure alcohol out of an alcoholic drink with a physical change, since alcohol is a homogenous mixture?
Question Date: 2004-02-05
Answer 1:

In principle by changing the temperature you might be able to separate between two solvents say A and B (like alcohol and water in your question) to some extent, though you may not be able to separate them completely. You may end with two phases that one is A rich and the other is B rich. The exact change in temperature needed depends on the exact compositions of the solvents.
