When Iron metal is dipped into a solution of copper sulfate a REDOX reaction occurs in which the Copper is reduced (gains electrons) and the iron is oxidised (loses electrons). When this happens, the iron metal becomes iron ions and the copper ions in the solution become copper metal.

Cu2+(aq) + 2e- --> Cu(s)

Fe(s) -->Fe2+(aq) + 2e-

This occurs because the iron is a more active metal than copper, and as a general rule of thumb, a more reactive metal will displace a less reactive metal from solution. This principle underlies the action of the sacrificial electrode.

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.


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


What happens when copper wire is dipped in ferrous sulphate solution?

When copper wire is dipped in ferrous sulfate solution, a displacement reaction occurs where copper displaces iron from ferrous sulfate, forming copper sulfate and iron. As a result, the copper wire will become coated with a reddish-brown deposit of iron.

Formula for Iron nail dipped in copper sulphate solution?

When an iron nail is dipped in copper sulfate solution, a displacement reaction occurs. The iron nail will displace the copper from the copper sulfate solution to form iron sulfate solution and copper metal deposits on the nail. This reaction is represented by the equation: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s).

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 happens to gold when dipped into a solution of copper sulfate?

When gold is dipped into a solution of copper sulfate, a redox reaction occurs where copper ions in the solution gain electrons and are reduced to solid copper metal. The gold does not react and remains unchanged in the solution.

Why does the blue colour of copper sulphate disappear when a zinc plate is dipped into it?

The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.

What happens when copper plate is dipped in ferrous sulphate solution?

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.


When zinc rod is dipped in a solution of aqu copper sulphate copper is precipitated out?

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


What happens when strip of zinc is dipped in copper sulphate solution?

When a strip of zinc is dipped in copper sulfate solution, a single displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the copper sulfate solution, forming zinc sulfate and depositing elemental copper on the strip. The solution changes color from blue (due to the copper sulfate) to colorless as zinc sulfate forms, and copper can be seen as a reddish-brown precipitate on the zinc strip.


What happens when zinc granules are dipped in copper sulphate solution?

When zinc granules are dipped in copper sulfate solution, a displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the solution, resulting in the formation of zinc sulfate and elemental copper. The solution changes color from blue (copper sulfate) to colorless (zinc sulfate), and reddish-brown copper deposits can be seen on the zinc granules. This reaction highlights the reactivity series of metals, where zinc is higher than copper.


What happens with gold dipped in iron sulphate solution?

Nothing. Gold is a noble metal- it is not displaced by iron.
