One is that when a hydrate is heated up, it will change colors indicating that there is a reaction occurring. Also, that the color change is a physical change since the anhydrous Copper (II) Sulfate could be hydrated again by adding water. When the water is added back to the compound, heat is released and it sizzles as it re-hydrates. Another thing I learned was that you could evaporate the water in a compound to make it an anhydrous compound. Lastly that the hydrate is chemically bound to the Copper (II) Sulfate, but it can be separated with
