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.

∙ 12y agoDissolve the copper sulphate powder in water and make a saturated solution, then warm it & dissolve more copper sulphate powder in the same (saturated) solution till it become super saturated solution. Filter this super saturated solution through a filter paper immediately. allow the filterate to cool at room temperature, crystals of copper sulphate will develop.

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
What is the boiling point of copper sulfate and water?
The boiling point of pure copper is 2835K/2562C/4643F.
Is copper pure form?
yes copper is a pure form
Is copper homogeneous or heterogeneous?
Neither. Copper is not a mixture at all. It is a pure element.
Is copper chloride a mixture?
No, copper chloride is a pure substance.
Which methods is used to obtain pure copper sulphate from impure sample and how?
by crystallisation, we can get pure copper sulphate crystals

How can you separate pure copper sulphate from an impure sample?
Dissolve in water and crystallize once more. The resulting crystals will be purer, while the remaining solution will comprise of the dopants + copper sulphate
Is copper sulfur a pure substance or a mixture?
There is no substance called "copper sulphur". You could have a mixture of copper and sulphur, though. But there are compounds (pure substances) of copper and sulphur as well. They include copper I and copper II sulphide (Cu2S and CuS). Another, very common compound is copper sulphate, CuSO4
Is copper sulphate a substance?
Copper Sulfate CuSO4 or Cu2SO4 is a chemical compound which can only be broken down by chemical means, so yes it is a pure substance.
Is copper sulphate a mixture or an element?
It is a compound. ---------------------------- Copper sulphate is a compound (a salt) made up of the elements Copper and Sulfur and Oxygen (CuSO4).
Is the water from the blue copper sulphate crystallines' pure water?
If the reaction occurs in normal atmospheric circumstances then yes, it should be
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate
What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
Why copper cannot displace iron from iron sulphate solution?
Iron is more reactive than copper. In other words, compared to copper, iron is more stable in a compound while copper is more stable as a pure element than iron is.
How do you purify copper sulphate?
By the method of electrolysisCopper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The extraction of copper from copper ore is done by reduction with carbon, but the copper produced is not pure enough for use as a conductor, so it is purefied using electrolysis.
