Water vapors and sulfur dioxide are released.
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
It is likely the substance was a salt such as sodium chloride or copper sulphate that was in solution. When the water evaporated it left the solid salts behind.
Copper sulfate is formed.
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
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.
copper sulphate and hydrogen is released.
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.
Copper sulphate pentahydrate loses water of crystallisation and becomes white amorphous anhydrous copper sulphate.
they dissolve or dilute

synthesis of coppersulfhydryloxalate
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
when blue Copper sulphate is heated, it loses its water part of crystallisation and tuns into white, anhydrous copper sulphate crystal
It makes copper sulphate + water :)
The reaction is;CuSO4 = CuO + SO3
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
