I am growing copper (II) sulfate pentahydrate crystals and need to recover some of the copper (II) sulfate pentahydrate that I mixed in water. I do not fully understand hydration and rehydration. If I heat the solution to boil away water, will the copper (II) sulfate pentahydrate dehydrate to its anhydrous form?
If no: great
If yes: how do I rehydrate the crystals so that I can dissolve them in the same concentration as my initial solution?
