      May 06, 2014 · A hydrate is a compound that has water molecules within its crystal structure. The formula for the hydrate CuSO4•5H2O(s) shows that there are five moles of water for every one mole of CuSO4(s). When CuSO4•5H2O(s) is heated, the water within the crystals is released, as represented by the balanced equation below.
