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.
What else can I help you with?
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 used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
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 Sulphate is a chemical compound w/ a chemical formula CuSO4 .
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 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.

How can you get copper sulphate from an impure sample?
1. Dissolve the copper carbonate/sulfate salts in water and filter it: the Copper Carbonate is insoluble so it will remain as the residue on the filter paper, and the copper sulfate is soluble so it will pass through the paper as the filtrate. 2. Heat the filtrate in an evaporating basin till the point of crystallization (crystals will form on a rod dipped into the mixture, at the point of crystallization). 3. Leave the filtrate to cool and crystals of pure Copper sulfate will form. Collect the crystals with a spatula and leave them on a sheet of filter paper to dry.

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?
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.
