actually blue salt of copper sulphate is chemically copper sulphate penta hydrate( CuSO4.5H2O ). blue coloure is due to thiese 5 moles of water . by heating this water evaporates and leaving CuSO4 which is colourless
it starts changing to white because the colour of the copper sulphate solution becomes whote during the process of evaporation
when blue Copper sulphate is heated, it loses its water part of crystallisation and tuns into white, anhydrous copper sulphate crystal
it smells like,,,chanel number 7(for men)
Copper Sulphate CuSO4Since the question did not include Oxygen, the answer is Copper Sulphide (CuxSx)If you have only Copper and Sulphur reacting the product is Copper Sulphide (CuS), not Copper Sulphate (CuSO4).Copper Sulphide is made when Copper and Sulphur are heated together - the product is a black solid.Copper Sulphate is produced when Copper is reacted either with sulphuric acid, or with a less reactive metal sulphate. Copper Sulphate is usually in the form of a blue solution but can be evaporated to produce a blue crystalline structure.
The copper becomes black!
Copper sulphate pentahydrate loses water of crystallisation and becomes white amorphous anhydrous copper sulphate.
The formula of the blue crystals of copper sulphate is CuSO4.5H2O. When they are heated mildly, the water from the crystals evaporate, giving just CuSO4. This 'anhydrous' form of copper (II) sulphate is white in colour.
Blue copper(II) sulfate (CuSO4), when heated, loses 5 water molecules per formula unit of water of crystallization. Its lattice structure collapses, giving it different physical properties, i.e. color.

It makes copper sulphate + water :)
The reaction is;CuSO4 = CuO + SO3
Examples of reversible chemical reactions - hydrous copper sulphate (blue) heated becomes anhydrous copper sulphate (white). When water is added, the reaction is reversed. Nitrogen dioxide (reddish brown gas) reacts to form colourless dinitrogen tetroxide, this reaction can go the other way also. Hydrogen and oxygen react to form water. This molecule can be split back into hydrogen and oxygen through electrolysis.
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
