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.

What is The name of the copper sulphate after being heated?
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
Do copper sulphate crystals have cleavage planes?
yes they do
How long does it take to grow copper sulphate crystals?
It can take a couple of days.
What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
How will you obtain pure copper sulphate crystal?
boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.
How would the crystals of copper sulphate be prepared?
melt the copper sulfate and see what appers
What equipment would be needed to prepare copper sulphate crystals?
Anhydrous or hydrated copper sulphate crystals? And from what?
Why blue crystals of copper sulphate on heating turn colourless?
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.

Which methods is used to obtain pure copper sulphate from impure sample and how?
by crystallisation, we can get pure copper sulphate crystals
Do copper sulphate crystals have cleavage planes?
yes they do
Are copper sulphate crystals good conductors of electricity?
no
Can copper sulphate crystals dissolve in water?
yes
Are copper sulphate crystals soluble?
Yes, in a saturated copper sulfate solution.
What happens when copper sulphate is dissolved in water?
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?

What colour are copper sulphate crystals?
very dark blue
