Mixing CuSO_4 and H_2O, heat was produced during the reaction. Why did that happen?
Mixing copper(II) sulfate (CuSO4) with water (H2O) generates heat due to the exothermic nature of the dissolution process. The dissociation of copper and sulfate ions releases energy, although the heat of hydration plays a crucial role in this reaction. When mixing CuSO4·5H2O with water, the heat released is significantly less, indicating that the hydration energy is less impactful in this specific case.
