Methods:

1. Measure and record of the mass of the crucible and lid on its own. 

2. Heat, cool and remeasure the mass of the crucible and lid until two measurements are 10 mg of eachother.

3. 1.761g of hydrated copper sulfate is added to the crucible.  

4. The crucible, lid, and hydrated copper sulfate is measured.

5. Gently heat the crucible, lid and hydrated copper sulfate for 3 minutes then increase heat for 3 minutes.  

6. The sample is checked to see if it turned white.  

7. If the hydrated copper sulfate did not turn white then it has to be heated for longer.

8. When the sample is white, it is cooled, measured and heated again.  

9. This process is repeated until the masses are within 10 mg of each other.

10. After the experiment has ended, a few drops of deionized water is added into the anhydrous sample to watch the reaction reverse (turn white to blue again).

11. Appropriate cleanup is performed, and materials are placed back in their right spots.
