Part 3: Reversibility of hydration 1. Transfer a small amount of solid copper (II) sulfate pentahydrate, CUSO,-5H,O, that just fills the bottom of a clean, dry 150-mm (medium size) test tube. 2. Using a test tube holder, grasp the test tube containing the hydrate and heat over a Bunsen burner flame while holding the test tube at a 45° angle. 3. While heating, closely observe the solid and the inside wall of the test tube. Record your observations. 4. When the solid residue seems to be completely dehydrated, allow the test tube to cool completely. Then, add a few drops of laboratory water to the solid in the test tube. What changes did you see? Record your observations. Appearance of CUSO..5H2O: Appearance of solid after heating: Appearance of the inside wall of the test tube after heating: Appearance of solid residue after adding a few drops of laboratory water:
