The anode is the electrode at which oxidation occurs, and the cathode is the electrode at which reduction occurs. ... Theory of Electroplating: Plating is governed by Faraday's Laws that state:
WebElectroplating is a process by which a metal is deposited on any other metal by passing current in the electrolyte. The basic principle is the electrolysis, i.e. the decomposition of the electrolyte used. The material to be deposited is made as anode and where deposited as cathode. For electroplating the d.c. low voltage is used upto 25 V or so. WebElectroplating, also known as electrodeposition, is essentially a chemical reaction that helps to make various items we see and use every day. There are also specific types of electroplating such as copper plating, silver …
