The set up below shows the process of electroplating of an article with silver. [ 51Electroplating is the process of depositing a thin layer of a superior metal(such as nickel, gold or silver) on the clean surface of a baser metal(such as copper or iron) by the process of electrolysis.Nandini wanted to electroplate her bracelet with silver.a) Name the electrolyte she should use.b) Write the reaction taking place at cathode.c) State the observation at anode.d) What will Nandini observe if she interchanges the terminals to which the braceletand silver plate are connected? Justify your answer.

a) The electrolyte she should use is Silver Nitrate (AgNO3).

b) The reaction taking place at the cathode is the reduction of silver ions to silver metal. This can be represented by the equation: Ag+ + e- → Ag

c) At the anode, the silver metal is oxidized to silver ions. This can be observed as the silver anode slowly dissolving into the electrolyte solution. The equation for this reaction is: Ag → Ag+ + e-

d) If Nandini interchanges the terminals to which the bracelet and silver plate are connected, the silver will be deposited on the new cathode (which was previously the anode). The bracelet, now connected to the anode, will start to dissolve into the electrolyte solution. This is because during electrolysis, reduction occurs at the cathode (where metal is deposited), and oxidation occurs at the anode (where metal dissolves).
