### Copper(II) Sulfate Pentahydrate Experiment

#### Measurements and Observations

1. **Mass of empty crucible**: `11.88 g`
2. **Mass of crucible plus hydrate**: `12.37 g`
3. **Mass of hydrate taken**: `0.49 g`
4. **Appearance of hydrate**: Blue coloration, salt

5. **Theoretical mass of H₂O lost expected on heating hydrate**: 

6. **Mass of crucible + anhydrous CuSO₄ after heating**: `12.30 g`

7. **Mass of anhydrous CuSO₄**: `0.42 g`
   - (Calculated as: Mass of crucible + anhydrous CuSO₄ after heating – mass of empty crucible)

8. **Mass of water lost from hydrate crystals**: `0.07 g`
   - (Calculated as: Mass of hydrate taken – mass of anhydrous CuSO₄)

9. **% error in mass water loss from hydrate**: 

10. **% of water loss**:

11. **Appearance of CuSO₄ after heating**: White / clear

12. **Appearance of CuSO₄ on adding water**: Blue
