Electroplating (electrodeposition) 2). Reaction surface Electroplating is to produce a dense, uniform, and adherent coating for decorative and protective purposes, or enhancing specific properties of the surface. The surface can be conductors, such as metal, or nonconductors, such as plastics. The coating is upon a surface by the act of electric current. The rate of reaction would vary due to the size of surface area. For those which have a broader surface would be coated more quickly, since the surface area continuously supplied with negative electron, therefore ions in the solution would be attracted and reduced in a faster rate. For those which have a smaller surface area would take a longer time to be reduces, as ions have to compete more vigorously for a spot of the surface in order to accept the electrons from the target surface.

Redox reaction Cathode (reduction) Anode (oxidation) Ag+(aq)+ e- → Ag(s) Ag(s) → Ag+(aq)+ e- The oxidized Ag from anode would migrate to the cathode and reduce, the purpose of putting Ag in the anode rather than other kind of metal is the ensure there are continuous supply of Ag+ ion in the solution so to coat a layer of silver onto our target (fork). The amount of substance produced or consumed in an electrolysis reaction is directly proportional to the quantity of electricity that flows through the circuit. The mass of the coating metal formed is proportional to the quantity of the electricity used. Works Cited "Chemistry: Faraday's Laws - CliffsNotes."
