Hydrated copper sulfate, CuSO4·5H2O, contains 36.10% water by mass.
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
You would get water in the gas phase (steam). The word "hydrated" means that there are water molecules mixed in with the copper sulphate, and so when you heat it, you will turn that water into steam, freeing it. Because of the high melting point of ionic compounds like copper sulphate, it will not be affected by heating unless you go to extemely high temperatures.
The formula of hydrated copper(II) sulfate is CuSO4•5H2O. The dot is used to indicate that the water molecules are present as part of the crystal structure of the compound.
copper sulphate gets hydrated in water and thus is diffusible.

On heating hydrated Copper Sulphate (CuSO4 . 5 H2O), the result is the removal of water molecules of crystallization, which for this very compound is 5 molecules per molecule of copper sulphate. The process cited above is termed as dehydration.
Anhydrous copper sulfate (CuSO4) is reversible in the sense that it can absorb water molecules from the environment to form hydrated copper sulfate. Conversely, hydrated copper sulfate can be heated to drive off the water molecules, regenerating anhydrous copper sulfate. This process is reversible as it involves only physical changes and not chemical reactions.

Water vapors and sulfur dioxide are released.

Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
Blue, because the copper cations become hydrated and the hydrated ions have a blue color.
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
