Electroplating

Here's well look at more details of electroplating. We'll talk about oxidation and reduction, anodes and cathodes. We'll write half reactions for the two processes that are happening in the electroplating cell. How does electroplating work? It is a process where you usually take an object made of one type of metal, and cover it with a thin layer of another type of metal. Usually, precious metals like gold, silver, or platinum are the metals that are electroplated. In an electroplating cell, electrons are removed from one of the metals, which is an oxidation process that happens at the anode. This causes the metal to develop a charge turn into an ion, and allows it to dissolve in the solution. Then, at the cathode, reduction takes place, and the metal ion turns into a neutral atom, and sticks to the surface of the other metal.
