C    H    Chemistry experiment electroplating What is Electroplating: Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. The materials used in the plating (coating) process depend on the composition of the plating bath and the deposition conditions. Electrolysis is used to electroplate objects (coat them with a thin layer or metal). 03 Chromium plating. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material. At the cathode (the part being plated), reduction is occurring. F    Q    Several parameters, such as electroplating equipment, electrolyte chemistry, power supply, electrolyte flow, and surface conditions affect the actual metal deposition inside the vias [39]. Electroplating occurs when an electrically conductive object is coated with a layer of metal using electrical current. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. Settings In the scientific study of chemistry, the process of electrolysis involves using direct electric current to prompt a chemical reaction which otherwise would be non-spontaneous. Home Economics: Food and Nutrition (CCEA). Electroplating necessitates the use of electric currents. Electroplating, on the other hand, uses electrolysis where a DC current dissolves a copper rod and the copper is then distributed on the surface. Features: There are two types of chrome plating. For example, the bumpers of cars are chromium-plated to protect them from corrosion. E    T    The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode.
