Because iron is a more reactive metal than copper.
The most common technique for converting a copper sulfate solution into solid copper sulfate is through evaporation. This involves heating the solution to allow the water to evaporate, leaving behind solid copper sulfate crystals. The process can be carefully monitored to ensure the crystallization of pure copper sulfate.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Copper sulfate solution is a liquid mixture containing copper ions and sulfate ions. It is commonly used as a fungicide, herbicide, pesticide, and in various industrial applications. Copper sulfate solution is blue in color and should be handled with care due to its potential toxicity.
Sodium hydroxide (NaOH) is an insoluble base that can be used to make copper sulfate. When sodium hydroxide is added to a solution of copper sulfate, a blue precipitate of copper hydroxide forms. This precipitate can be filtered and then reacted with sulfuric acid to produce copper sulfate.
Oh, dude, it's like this - you take the steel wool and just plop it into the copper sulfate solution. The steel wool reacts with the copper ions, forming a solid copper metal on the wool and leaving the solution without the Cu2+ ions. It's like magic, but with science!
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
Iron is more reactive than copper
Since iron (Fe) is more reactive than copper (Cu) it will be 'plated' with copper when the metal iron is stuck in copper sulfate solution. Fe(s) + Cu2+(aq) + [SO42-]aq ---> Fe2+(aq) + Cu(s) + [SO42-]aq
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.
Copper can be obtained from copper sulfate solution by electroplating it onto an electrode or by adding a metal higher in the electromotive series than copper, such as iron, to the solution. The more active metal will dissolve by displacing copper in metallic form from the copper sulfate.
Copper sulfate is not used as an iron supplement. It is a source of copper, which is a different nutrient necessary for various biological processes in the body. Iron supplements typically contain forms of iron such as ferrous sulfate or ferrous fumarate.
Crystallization is commonly used to purify copper sulfate. The solution containing copper sulfate is heated to dissolve the impurities, then cooled slowly to allow copper sulfate crystals to form and separate from the impurities. The pure copper sulfate crystals can then be separated from the solution through filtration.

In general, any metal higher than copper in the "electromotive series" will displace copper from copper sulfate solution. This category includes all the alkali and alkaline earth metals and other common metals such as iron and zinc. For example Aluminum and Iron both displace Copper: Aluminum in Copper sulfate will trade places in the ionic balance of the solution and 'join' with the sulfate. CuSO4(aq) + Al(s) ==> AlSO4(aq) + Cu++(s) Because this single displacement reaction occurs in immediate proximity to the aluminum, Copper++ ions accumulate in a fluffy rust colored fur around the aluminum. Iron in Copper Sulfate will also go into the aqueous sulfate solution and the Copper will precipitate onto the Iron CuSO4(aq) + Fe(s) ==> FeSO4(aq) + Cu?(s) This reaction happens at the ferrous surface more intimately than the Aluminum and the Copper is deposited as a 'plate'.

Copper sulfate can be separated from a solution by methods such as filtration, evaporation, or crystallization. Filtration can be used to remove any solid copper sulfate from the solution, while evaporation can be employed to concentrate the solution and allow the copper sulfate to crystallize out. Crystallization involves cooling the solution slowly to encourage the formation of pure copper sulfate crystals which can then be separated.
One method to separate copper from a copper sulfate solution is through electrolysis, where an electric current is passed through the solution to deposit the copper onto a cathode. Another method is to add a more reactive metal, such as iron, which will displace the copper from the solution through a displacement reaction.
