what advantages does water have as a crystallization solvent?

Question

Aside from its polarity and being easily available. It is in relation with organic chemistry, specifically, purification of organic compounds by the crystallization technique. Thanks!

Answer 1

It is only useful for crystallization of solutes which are at least partially soluble in water.
You mention polarity and availability.
It is also well-behaved over a useful range of temperatures, is non-flammable and non-explosive, chemically stable, non-toxic, easy to distill off or evaporate, clear and colorless, and cheap.
