If an iron nail is placed in a copper(II) sulfate solution, the iron ions are exchanged with the copper ions, creating iron sulfate and copper (which precipitates out as copper metal).
Fe + CuSO4 --> FeSO4 + Cu
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
When iron nails are placed in copper sulphate solution, a displacement reaction occurs where iron replaces copper in the solution to form iron sulphate and copper metal. The word equations for the reactions involved are: Iron (s) + Copper sulphate (aq) -> Iron sulphate (aq) + Copper (s)
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.
a single replacement reaction
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
Copper is a less reactive metal than calcium, therefore it cannot replace the calcium in the calcium sulphate. Refer to the related link for a reactivity series.
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
To copper-plate another metal, the procedure is pretty simple. You need a DC power source, a bath of copper sulphate, and a copper electrode. Connect the positive terminal of the battery to the copper electrode, and the negative to the item to be plated. When the copper electrode and the item are placed in the copper sulphate solution, the circuit is complete and copper electrons will stick to the item.
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.
Zinc is more reactive than copper sulfate. When zinc is placed in a solution of copper sulfate, a displacement reaction occurs where zinc displaces copper from the solution, forming zinc sulfate and copper metal.
When a crystal of copper sulfate is placed in water, it dissolves and releases copper ions into the water. These copper ions give the water a blue color due to the absorption and reflection of certain wavelengths of light. This color change is a result of the presence of the copper ions in the solution.
When a silver rod is placed in a blue copper sulphate solution, there is no visible color change because silver is less reactive than copper. This means that silver does not displace copper from copper sulfate solution during the reaction, so the blue color of the copper sulfate solution remains unchanged.
