In electroplating, what is the purpose of the metal ions in the solution?

Step 1: Understand that electroplating is a process used to coat a surface with a layer of metal.
Step 2: Know that the solution used in electroplating contains metal ions, which are tiny charged particles of metal.
Step 3: Recognize that during electroplating, an electric current is passed through the solution.
Step 4: Learn that the cathode is the part of the setup where the metal will be deposited.
Step 5: Realize that the metal ions in the solution move towards the cathode when the electric current is applied.
Step 6: Understand that at the cathode, the metal ions gain electrons (this is called reduction) and turn into solid metal.
Step 7: Finally, see that this solid metal is deposited onto the surface of the object being electroplated.
