Copper sulfate in its solid crystal from present as pentahydrate (CuSO4 5 H2O). When heated strongly it loses water molecules and becomes CuSO4. Note that CuSO4 5 H2O is blue in color whereas CuSO4 is colourless since absorption region shifted from visible region. On further heating it is dissociated to CuO.

When you heat copper(II)sulfate pentahydrate (a blue compound), you dehydrate the compound, which means you remove the water. The dehydrated compound is white. You can add water to this to rehydrate the compound, and turn it back to blue.

The equation for the dehydration of copper(II)sulfate is:

CuSO4o5H2O --> CuSO4 + 5H2O

On the reactant side the copper(II)sulfate is chemically bonded to the 5 water molecules. On the product side, the water is no longer bonded. (You should be able to see it on the mouth of the test tube if you heat the substance in a test tuve under a Bunsen burner)

What is the chemical formula for iron and copper sulfate?

The formula for iron is Fe. The formula for copper sulfate is CuSO4. The chemical equation for the reaction is Fe (s) + CuSO4 (aq) --------- Cu (s) + FeSO4(aq) The iron is a more active metal than copper therefore it replaces the copper in the copper sulfate solution.
