A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation:
Copper sulphate + Iron = Iron sulphate + Copper
solution
(CuSO4) + (Fe) = (FeSO) + (Cu)
It isn't displaced as gold is less reactive than copper sulphate!
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
That's a good question. What didhappen to it?I wouldn't expect much of anything to happen, since copper is a more active metal than silver. In fact, a copper plate dipped into a silver nitrate solution should grow silver crystals as the copper ionizes and replaces silver in solution.
Zinc becomes plated with copper.
After a while you will observe that the nail has become coated with a layer of copper. This is a single displacement reaction since iron is more reactive than copper CuSO4 + Fe = FeSO4 + Cu
no reaction would take place
It isn't displaced as gold is less reactive than copper sulphate!
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
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.
The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.
Zinc is higher than copper in the electrochemical series, so it will displace copper from it's solutions.Zn + CuSO4 = ZnSO4 + CuCopper plates onto the zinc as a small amount of zinc sulphate is produced.
There would be no reaction because copper is a less reactive metal than iron. Refer to the related link for an activity series of metals.
This is due to something called a displacment reaction, during a displacment reaction one of the particals from one of the substances "swap" with another partical from the solution In the case of zink and copper sulphate solution, the copper and zink 'switch places to produce copper and a solution of zink sulphate. This is how, A + BC = B +AC
Nothing. Gold is a noble metal- it is not displaced by iron.
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
