Nova was passed on a silver locket from her grandmother. The locket had a lot of chip marks uponinspection. She wants to restore the locket, so she devised a plan to electroplate silver from an ore ontothe surface of the locket. Nova proceeded with the electroplating process, however, she realized thatthe concentration of the silver ions present in the solution is unknown. She decided to use a galvanic cellto obtain the silver ion concentration. She used the half-cell reactions below:Ag*(ag) + e - Ag(s)E°+0.800VPb2* (aa)+ 2e - Pbs)E°= - 0.125VGiven:[Pb2+] = 1.0 MEMPb = 207.2 g/molFMAR = 107.9 g/mol1. What is the cell notation of the set-up?2. What is the standard cell potential?3. The measured cell potential is 0.928V, what is the concentration of Ag: ?After determining the silver ion concentration, Nova then electroplated the locket using 500 mLof the silver solution with a current of 5.0A.4. How long (in hrs) will it take to electroplate the locket assuming that all silver ions areconverted to silver metal?5. What is the mass of the electroplated silver?

The question is based on the concept of electrochemistry. the electrode which has higher reduction…
