Hydration
From Wikipedia, the free encyclopedia.
In chemistry, hydration has two related but different meanings. One meaning is that hydration is the act of creating a hydrate. In a hydrate, water can be removed from the product. The other meaning is that hydration refers to a hydration reaction, in which water is permanently and chemically combined with a reactant (an alkene, for example) in an way that it can no longer be reextracted.
