Electric Plating

Electroplating is a technique of depositing a thin film of another metal on the surface of a metal.

(-) The electrode is connected to the object to be plated,
(+) The electrode is connected to plating material such as gold, silver, nickel.
Two metals are soaked in an ion solution that has the same metal to be plated.

In this case, in the (-) electrode, the ions are reduced and plated, and in the (+) electrode, the metal is oxidized to become an ion.

(+)electrode (oxidation): Ag(s) → Ag+(aq) + e-
(-)electrode (reduction): Ag+(aq) + e- → Ag(s)
