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.
To obtain pure copper sulfate crystals, you can start by dissolving copper sulfate in water to form a saturated solution. Then, allow the solution to cool slowly, which will encourage the formation of crystals. Finally, filter the solution to separate the crystals from the remaining liquid and allow the crystals to dry to obtain pure copper sulfate crystals.
Dissolve 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.
Simply cool the solution further. When cooled, the solubility of Copper (II) Sulfate decreases, causing further forming of crystals.
Well, i only know how to obtain a pure copper (2) sulfate crystal. It is done by crystallization. But it is a very long process!

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
Why you use alcohol in preparation of tetraamine copper 2 sulphate monohydrate?
we use ethanol to decrease the solubility of ammonia in water,so that ammonia easily combines with copper in less polar environment now..in this way solubility is decreased and the complex i.e tetraammine copper 2 sulphate crystallizes out..
Is copper found in its pure state?
Copper is often found in its pure state as a native metal in nature. It is commonly found in the form of nuggets or as part of mineral deposits. Mining and extraction processes are then usually used to obtain copper in pure form for various commercial and industrial applications.
Is copper pure form?
No, copper is typically not found in its pure form in nature. It is usually found in combination with other elements in ores, which must be processed to extract the pure copper metal.
Is copper wire a pure substance?
No, copper wire is not a pure substance because it is made up of copper atoms as well as impurities or alloying elements. Pure copper would be a pure substance, but copper wire is typically a mixture of copper and other elements.
Which methods is used to obtain pure copper sulphate from impure sample and how?
One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
Is pure copper sulphate a mixture?
No, pure copper sulfate is not a mixture. It is a compound composed of copper, sulfur, and oxygen atoms in a fixed ratio.
Is copper sulphate a metal?
Copper sulfate is a chemical compound, not a pure metal. It contains copper, sulfur, and oxygen. Copper itself is a metal that can form different compounds like copper sulfate.
Why does one of the reactant copper carbonate is added in excess when preparing a sample of copper sulphate crystals?
Excess copper carbonate is added to ensure that all the copper sulphate is fully converted. This helps to make sure that all the starting material is used up and that the reaction goes to completion, resulting in a higher yield of pure copper sulphate crystals.
How can you get copper sulphate from an impure sample?
To obtain copper sulfate from an impure sample, you can first dissolve the sample in water to create a solution. Then, filter the solution to remove any insoluble impurities. Finally, crystallize the solution by evaporation to obtain pure copper sulfate crystals.
How can you separate pure copper sulphate from an impure sample?
You can separate pure copper sulfate from an impure sample by dissolving the sample in water to create a solution. Pure copper sulfate will remain dissolved, while impurities will either remain undissolved or form a precipitate. You can then filter the solution to separate the impurities from the pure copper sulfate solution, which can be recovered by evaporating the water.

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
What is the reaction between iron and copper sulphate?
When iron is added to copper sulfate solution, a single displacement reaction occurs. The iron displaces the copper in the compound, forming iron sulfate and leaving behind pure copper. The balanced chemical equation for this reaction is: Fe(s) + CuSO4(aq) -> FeSO4(aq) + Cu(s).
Is the water from the blue copper sulphate crystallines' pure water?
If the reaction occurs in normal atmospheric circumstances then yes, it should be
How do you purify copper sulphate?
To purify copper sulfate, you can dissolve the impure copper sulfate in water, filter out any insoluble impurities, then evaporate the water to obtain pure copper sulfate crystals. You can also perform a recrystallization process by dissolving the impure copper sulfate in hot water, allowing the solution to cool and crystals to form, then filter out the pure crystals.
