You need to start with a copper compound and react it with an acid to get the salt you want. If you use hydrochloric acid you will get a chloride; if you use nitric acid you will get a nitrate. You asked for copper sulphate so can you decide for yourself which acid you need? You will need to put this in a conical flask and heat it - if you're heating acids you must wear protective goggles - and add some copper oxide. This is black. It will react and form a blue solution. You need to be sure you have used up all your acid so you must use enough copper oxide to have some left over. Stop heating and filter it to get rid of the rest of the copper oxide. You want to get rid of the water now - if you want to be quick you can evaporate it by placing it in an evaporating basin on top of a beaker of boiling water. If you have time you can just leave it to evaporate slowly at room temperature. If you do it this way you will get nicer, bigger crystals. Why do you think this is? Look carefully at your crystals to see what shape they are.
Anhydrous or hydrated copper sulphate crystals? And from what?
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.
by crystallisation, we can get pure copper sulphate crystals
no
yes
melt the copper sulfate and see what appers

yes they do
no
yes
Yes, in a saturated copper sulfate solution.
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?
very dark blue
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
