For our chapter project, we are studying electroplating. "What is electroplating?" you say? Electroplating is the process of using electric current to coat a layer of metal onto the surfaces of another material.

-Electroplating was invented in 1805 by Luigi Brugnatelli.
-One usually Electroplates with silver or gold to make an object appear more valuable.
-The flow of electrons from a battery is needed to reduce the metal ions. When the metal ions are reduced, objects become plated with metal.
-Electroplating is widely used for covering art pieces such as sculptures, with a smooth coating.
-Electroforming is a type of Electroplating that is created from layers of metal that form within and around a mold.
-Another type of Electroplating is Displacement/Electrochemical plating which is when you electrically plate one metal onto another metal without
using a battery.

Here is a link to an experiment to easily electroplate a penny.

Heres how electroplating works: First, a metal salt is dissolved into water to make a plating solution. Then, a solid piece of metal (the same metal as the metal salt) is placed in the solution. This becomes the anode by connecting it to the positive pole of a battery. The object that will be plated in the metal (in this case, it is a spoon) is placed in the solution. This becomes the cathode by connecting it to the negative pole of the battery. The electric circuit that is created allows electrons to flow from the anode to the cathode. The flow of electrons makes the metal ions reduce, and the plating of the metal begins.
