Anhydrous (without water) is an applied to minerals which do not contain water of crystallization or water of chemical combination. For example, strongly heated copper (II) sulphate pent hydrate (CuSO4•5H2O) produces anhydrous copper (II) sulphate (CuSO4). Less stable and more dangerous to use than hydrated.
