  • (Chem.), the water combined with many salts in their crystalline form. This water is loosely, but, nevertheless, chemically, combined, for it is held in fixed and definite amount for each substance containing it. Thus, while pure copper sulphate, CuSO4, is a white amorphous substance, blue vitriol, the crystallized form, CuSO4.5H2O, contains five molecules of water of crystallization.
