Q Can sugar be separated from water by freezing in the same manner as salt?
A Yes, I don't see why not.

Q Could Maple sap be condensed in this way?
A Yes, I don't see why not.


Q Could ice be used as a semipermeable membrane?

A. That sounds pretty impractical since ice is fragile, but there must be some instance where it would work. I believe protons travel much more easily through ice than do other ions.
