Copper is less reactive than Iron and hence, cannot displace Iron from any of its solutions. Anyhow, the reverse is possible ie, Iron can displace Copper from it's solution as it is more reactive than Copper.

Why can iron be used to get copper from copper sulfate solution?

Iron is more reactive than copper


What will happen when iron and iron react?

Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.


Why will iron displace copper from aqueous solutions of copper salts?

Because iron is more reactive than copper. If iron displaces copper, that releases energy (enthalpy). If copper were to displace iron, that would require energy to be used. This is less favourable and , averaged over the huge number of molecules, atoms and ions in the solution, the more energy producing reaction is vastly preferred. Hence, iron put into copper sulphate solution gets coated in copper and the solution slowly loses its blue colour. But if you put copper metal in iron sulphate solution, nothing noticable occurs.


How can iron be used to get copper from copper sulfate solution?

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


Which colour of copper sulphate solution change when iron dipped in it?

It may seem like the iron rusts, but it doesn't. The chemical formula for copper sulfate is CuSO4, or, 1 copper atom, 1 sulfur atom, and 4 oxygen atoms to each molecule. When the iron is placed in the solution of copper sulfate, it replaces the copper in the solution, turning copper sulfate into iron sulfate (FeSO4) and pure copper collects on the iron. This can be proved by removing the copper and seeing that the iron has lost a lot of its mass, as in, it lost mass to the copper sulfate. The iron (steel wool) takes on a pinkish color which is metallic copper deposited when the solution forms iron sulfate.

What happens when you add an iron III nitrate aq solution to copper?

Nothing. Copper is lower than iron in the electromotive series and will not replace the iron in the iron nitrate solution.


What happen when an iron nail is dipped in copper sulphate solution. why does the colour changes?

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.


Why copper cannot displace iron from iron sulphate solution?

Iron is more reactive than copper. In other words, compared to copper, iron is more stable in a compound while copper is more stable as a pure element than iron is.


Why does copper solution stick to iron nails?

Iron is more reactive than copper, so the copper precipitates out of the solution by sticking to the iron. For example, if you have a test tube with a solution of copper (II) sulfate and put an iron nail into it, the iron will react with the solution to form iron (II) sulfate and the copper will come out of the solution and stick to the iron.


Which of these metals will replace the Iron in an Iron Solution a copper b gold c Lead d Zinc?

Only Zinc


What change is expected in the reaction mixture if a copper wire is kept immersed in AN Iron sulphate solution?

No reaction, because iron is a more active metal than copper. This means that copper cannot reduce iron from its salt.


What happens when iron nail are placed in copper sulphate solution?

the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.


When iron nail is put into a beaker containing copper sulphate solution the blue colour of solution turns green why?

Iron is more reactive than copper and the ferrous (Fe++) ions will replace the copper (Cu++) ions in the sulphate. CuSO4 is blue, FeSO4 is green.

Can iron be in a copper color?

not pure iron... But you can provide a covering over iron to make it look like copper by just dipping it into copper sulphate solution .. Because Iron is more reactive than Copper ... it will displace it in the solution .. the color of solution will change so as the color of iron!


Why colour of copper sulphate solution changes to light green when iron filings are added?

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.
