(a)
Interpretation : The half reaction for given process needs to be determined.
Concept Introduction : Electroplating process involves an
(b)
Interpretation : If the ring act as anode or cathode needs to be determined.
Concept Introduction : Electroplating process involves an electrochemical reaction in which gold or silver is coated over other metal substances. Here when electricity is passed, the silver or gold ions discharge over other metal substance due to difference in their electrode potential.
(c)
Interpretation : The reason for need of energy to gold plate the ring needs to the explained.
