To electroplate an iron nail with a copper rod, set up an electrolytic cell with the iron nail as the cathode and the copper rod as the anode. Place them in a copper sulfate solution and pass a current through the cell. This will cause copper ions to be reduced at the iron nail, resulting in copper plating on the surface of the nail.

WHY DID THE IRON ROD KEPT IN COPPER SULPHATE SOLUTION TURNED BROWN AFTER SOMETIME AND WHAT OTHER CHANGE WILL YOU OBSERVE?
The iron rod turned brown because it underwent a chemical reaction with the copper ions in the copper sulfate solution, forming copper metal on the surface of the iron. Another change you might observe is that the copper sulfate solution may become lighter in color as some of the copper ions plate onto the iron rod.
When you heat a copper rod does it increases its mass?
Heating a copper rod does not change its mass. However, the density of the copper rod may change slightly due to thermal expansion, which can cause the dimensions of the rod to increase.
Why iron rod loos its shiny and rusted when in kept in open air?
Iron reacts with oxygen in the presence of moisture in the air to form iron oxide, also known as rust. This process is called corrosion, and it causes the iron rod to lose its shiny appearance and develop a reddish-brown coating. To prevent rusting, iron can be coated with a protective layer, such as paint or a metal plating, to inhibit its exposure to oxygen and moisture.
What happens when copper rod is immersed in silver nitrate solution?
When a copper rod is immersed in a silver nitrate solution, a redox reaction occurs where copper displaces silver from the solution to form copper nitrate and silver metal. This is due to copper being higher in the reactivity series than silver. As a result, the copper rod will become coated with a layer of silver metal while copper ions from the rod will transfer into the solution.
What happens to a copper rod if it is on fire?
When a copper rod is on fire, it will oxidize and produce copper oxide. The flames from the fire will be green or bluish-green due to the presence of copper ions. Eventually, the rod will likely melt if the fire is hot enough.

How to make electricy from a potato?
Insert two different kinds of metal rods into the potato and you should see voltage on a voltmeters. Try copper wire for one rod, and an iron nail for the other.
WHY DID THE IRON ROD KEPT IN COPPER SULPHATE SOLUTION TURNED BROWN AFTER SOMETIME?
The Iron rod(Fe) reacts with the Copper Sulphate. Substitution reaction takes place. Fe+CuSO4--> FeSO4 + Cu
What are the three important parts of electro magnet?
Battery/iron rod/copper wire.
What does an intergrated chip do?
i don't know about sprinkler but u can make it by a iron and a copper rod
What is the anode and cathode of Baghdad's battery?
the copper cylinder(cathode) and iron rod(anode)
The blue colour of the solution fades during the electrolysis of copper sulfate. Explain why.?
Why does the colour of copper sulphate solution change when an iron nail is 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 is copper rod?
it is a rod made of copper
What is iron rod?
iron rod
How do you weld cast iron with an oxy acetylene torch with a cast iron rod?
I am not aware of a cast iron rod for oxy acetylene welding, I am for arc welding, For cast, I use a brazing rod, a brass or copper alloy, but what do I know. If there is a cast rod available, it would be the same process, get the cast you are welding hot almost to the point of melting, bring in the rod, heat it at the same place and bring both to a melting point. Work from that point along the crack or joint you are welding. ----------------------------------------------------------------------------------------------------------------- You need not use brazing rod for case iron welding. You get arc welding electrodes for cast iron. Use appropriate grade of rod for your case iron under welding.
Is an iron rod a mixture?
If the rod is made from pure iron it is not a mixture.
When you heat a copper rod does it increases its mass?
Heating a copper rod does not change its mass. However, the density of the copper rod may change slightly due to thermal expansion, which can cause the dimensions of the rod to increase.
