When we did it the other day what happened was this: the magnesium caused tiny bubbles and little dots of black fell to the bottom of the test tube (Copper I guess). When the reaction stopped, the liquid was still blue. We tried heating the mixture and got a bit more bubbles and 'dots' then we left the test tube for several days. Now the magnesium is coated with a pretty turquise coating of something, the solution is still blue, the dots are still black at the bottom of the tube. So CuSO4 + H2O + Mg should give you MgSO4 (which is soluble) and Cu. I do not know what we have actually got. The chemicals came from a chemistry set...the CaOH was equally not 'right' or rather it was far less 'basic' that I expected hmmm.
When magnesium strips are added to the blue coloured copper sulphate solution,
the colour of the solution disappears because magnesium is more reactive than copper.
It displaces copper from copper sulphate solution.
magnesium oxide is formed.

Magnesium is more reactive than copper in the reactivity series (reactive metal atoms displaces less reactive metal ions from its salts).therefore : Mg displaces CU from its salt forming MgSO4 (Magnesium Sulphate)
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.
Magnesium sulfate is a compound, and the terms metal a nonmetal do not apply to it.
If it's a non-metal and non-metal, it is a colvalent bond. If it's metal and non-metal or metal and metal, then it is ionic. Magnesium Sulfate (MgSO4 / Magnesium + Sulfate) is IONICbecause it is a metal and non-metal but it has a convalent bond in it, which is SO4 (Sulfur + Oxygen).
Copper sulfate solution starts of a blue colour. When Iron metal is added to the solution a REDOX reaction begins in which the copper is reduced (gains electrons) to become copper metal and the iron is oxidised (loses electrons) to become iron ions. When the iron ions go into solution, it will change to a green colour which is the colour of iron (II) sulfate. As a general principle, a more reactive metal will displace a less reactive metal from solution by the process described above.
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
Redox! The magnesium is reducing the copper while the copper is oxidizing the magnesium. In other words, magnesium is giving electrons to the copper to bring the copper back to its metallic form while the magnesium is leaving the metal to be part of the solution as magnesium sulfate, which is colorless.

Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.
Copper sulfate is not a metal There are two compounds called Copper Sulfate, which are salts of the metal Copper. CuSO4 is Copper (II) Sulfate, once known as Cupric Sulfate. Cu2SO4 is Copper (I) Sulfate, once known as Cuprous Sulfate.
They do not react.
Because iron is a more reactive metal than copper.
The iron which is a more electrochemically active metal gets plated with copper and iron sulfate is formed
Copper is a metal that cannot replace zinc from zinc sulfate solution. This is because copper has a lower reactivity than zinc and cannot displace it in a chemical reaction.
