Expert Answer:

Electroplating with Silver

Electrolyte: Na[Ag(CN)2] or K[Ag(CN)2]


Dissociation: Na[Ag(CN)2] rightwards arrow over leftwards arrow with blank on top  Na+ + Ag+ + 2CN

                                 H2O  rightwards arrow over leftwards arrow with blank on top  H+ + OH


Cathode: Copper bell

Anode: Pure silver

Electrodes reactions:

Reaction at cathode: Ag+ + e→ Ag (deposited)

Reaction at anode:    Ag − e→ Ag+ (goes into solution)
