What is Electroplating?
'''Electroplating''' is the [[wikt:coat|coating]] of an object with a [[metal]]. It is done by [[wikt:immerse|immersing]] the object and a bar of the metal in a [[Chemical solution|solution]] containing the metal [[ion]]s. [[Electric current]] is then applied; the [[Positive charge|positive]] goes to the metal and the [[Negative charge|negative]] goes to the object. The metal bar dissolves in the solution and plates out on the object, forming a thin but durable coating of metal. It is often used to [[gold]]-plate objects for [[wikt:decoration|decoration]] or to stop [[corrosion]]. Normally the metal becomes fragile, and is only used for display.
