Electroplating involves two reactions. At the cathode (shown above), the dicyanosilver(II) ion is reduced to silver metal where it is deposited. At the anode the opposite reaction occurs and silver metal dissolves.

When silver is complexed with cyanide ion a rather high potential (voltage) is required, and this increases the quality of the silver plating.
