When copper(II) sulfate pentahydrate (CuSO4•5H2O) is heated, it decomposes to the dehydrated form. The waters of hydration are released from the solid crystal and form water vapor.
The hydrated form is medium blue, and the dehydrated solid is light blue.
The balanced equation is:
CuSO4•5H2O(s) heat→ CuSO4(s) + 5H2O(g)
If 3.63g CuSO4•5H2O is decomposed to CuSO4, predict the mass of the remaining light blue solid.
