…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.
