When you heat hydrated copper sulfate, the color of the crystals turn from blue to white. This is because heat causes the crystals to lose their water of crystallization(which gives them a blue color). The loss of the water of crystallization turns the crystal to white. Blue crystals are hydrated. This gives them the formula of CuSO4. 5H2O (copper sulfate pentahydrate).

This is a reversible change because the white crystals can change color back to blue by adding water to them.
