Electroplating (Process and Example)
Electroplating is a fascinating application of electrolysis where a thin layer of metal is deposited onto a substrate (usually made of a different material) to enhance its properties. The process involves positioning the article to be plated as the cathode, which attracts negatively charged ions, and the metal to be deposited as the anode, from which metal cations dissolve into the electrolyte solution. A typical example is silver plating, where the cathode is the article needing plating, the anode is a pure silver electrode, and the electrolyte is a silver nitrate (AgNO₃) solution. This process not only provides aesthetic benefits but also offers protective qualities against corrosion.
