Because iron is more reactive than copper, as can be seen on an activity series of metals. Refer to the related link for more information and an activity series of metals.

What two colour changes do you get when you add copper sulphate solution to iron wool?

When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.


When an iron nail is put into a copper-sulphate solution there is a displacement reaction what does this mean?

A displacement reaction occurs when a more reactive element displaces a less reactive element in a compound. In this case, iron is more reactive than copper and displaces it in the copper-sulphate solution to form iron sulphate and copper metal.


What happens when an iron nail is dipped in copper sulphate solution?

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)


What is the chemical equation for when iron is added to copper sulphate iron sulphate is formed and copper falls to the bottom?

The chemical equation for this reaction is: Fe(s) + CuSO4(aq) -> FeSO4(aq) + Cu(s).Iron displaces copper from copper sulphate solution to form iron sulphate and solid copper precipitates out of the solution. This is an example of a single displacement reaction.


What will happen when iron and copper sulfate 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.

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.

Why does the color of copper sulphate change when an iron nail 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.

What happens when iron nail are placed in copper sulphate solutions with word equation?

If iron nails are placed in a copper sulphate solution they turn green and rusted which means they become copper plated nails.I think the word equation is :iron + copper sulphate - copper + Iron sulphate.Iron displaces copper

Iron nail dipped in copper sulphate solution?

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


Is there a fast reaction between iron and copper sulphate solution?

Yes, there is a fast reaction when iron is placed in copper sulfate solution. The iron reacts with the copper sulfate to form iron sulfate and copper metal. This results in a displacement reaction where the more reactive iron displaces the less reactive copper from the solution.

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

The color change occurs because the iron filings react with copper sulfate, forming iron sulfate and copper. This reaction results in a displacement reaction, where the iron displaces the copper in the compound. This changes the chemical composition of the solution, resulting in a light green color.
