by crystallisation, we can get pure copper sulphate crystals
copper sulphate is soluble.dissolve the two in water whereby cuso4 dissolves.filter the mixture the put the filtrate in an evaporating dish to evaporate excess water.do not evaporate to dryness coz some water ir required for crystalization.
The chemical equation is:CuSO4-----------CuO + SO3
crystilisation
it results in an impure liquid because filtration only filters out the sediments in the liquid. To obtain pure liquid you must use the distillation process
The spreading of blue colour of coppersulphate crystals in water is due to movement of water paticles as well as coppersulphate particles.due to the movement of particles the coppersulphate crystals and water particles mix with each other this is called diffusion.diffusion takes place untill the whole water obtain blue colour.
Crystallization
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
Chalk (Calcium carbonate) is insoluble. Copper sulphate is soluble. To separate, first place the mixture in wter. The copper sulphate will dissolve, the chalk will not dissolve. When the copper sulphate is fully dissolved, filter the solution. The copper sulphate component will pass through the filter paper, but the chalk will remain in the filter paper. Dry the filter paper to obtain the dry chalk. Evaporate the solution to dryness, to obtain the blue dry copper sulphate crystals.

Copper sulphate is a compound, so copper must be obtained through a chemical reaction. To obtain copper from copper sulfate, do the following: Place a piece of aluminum wire into a copper sulphate solution. Aluminum will replace the copper in the copper sulphate and copper will come out of solution and form along the aluminum wire, actually replacing the atoms of aluminum. The chemical equation is 2Al(s) + 3CuSO4(aq) ---> 3Cu(s) + Al2(SO4)3(aq). This kind of reaction is called a single replacement or single displacement.

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.
Blue vitriol is a very obsolete name for the copper(II)sulphate: CuSO4. Don't use in the future this term. Pentahydratated copper(II) sulphate: CuSO4.5H2O - bright blue color After the dehydratation of the above compound we obtain the anhydrous copper(II) sulphate: CuSO4 - pale green color.
