Hydrated

Inorganic chemistry

The notation "hydrated compound⋅nH₂O", where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated. The n is usually a low integer, though it is possible for fractional values to occur. For example, in a monohydraten = 1, and in a hexahydraten = 6. Numerical prefixes mostly of Greek origin are:
