The structure of the solid pentahydrate reveals a polymeric structure wherein copper is again octahedral but bound to four water ligands. For laboratory use, copper sulfate is usually purchased.

Anhydrous Copper sulfate is 39. 81 percent copper and 60. 19 percent sulfate by mass, and in its blue, hydrous form, it is 25. The second dehydration step occurs with the final two aqua groups are lost.

Complete dehydration occurs when the only unbound water molecule is lost. When water is then added to the anhydrous compound, it turns back into the pentahydrate form, regaining its blue color, and is known as blue vitriol.
