Purpose
*<Tab/>to verify that heat is released when a new bond is formed
*<Tab/>to calculate the amount of heat (cal/g) released when CuSO4 is hydrated by applying the specific heat formula (mass (g) x Δt°C x Cp)
CuSO4(s) + 5H2O(l)  CuSO4*5¬¬H2O(s)
Materials

amp;gt;The more H2O attached to the CuSO4 the darker shade of blue it is.
3.<Tab/>Water moisture from the air will attach to anhydrous CuSO4
Results
When 6 g of anhydrous cupric sulfate was hydrated, 44 calories of heat were released. This resulted in a 33% error.
Conclusion
When lab procedural mistakes are avoided, the amount of heat released when a crystal is hydrated can be determined by this lab method.
