Nova was passed on a silver locket from her grandmother. The locket had a lot of chip marks upon inspection. She wants to restore the locket, so she devised a plan to electroplate silver from an ore onto the surface of the locket. Nova proceeded with the electroplating process, however, she realized that the concentration of the silver ions present in the solution is unknown. She decided to use a galvanic cell to obtain the silver ion concentration. She used the half-cell reactions below: Ag*(ag) + e - Ags) - Agıs) E° - +0.800V Pb2*(ag) + 2e - Pb(s) E° = - 0.125v Given: [Pbz+] = 1.0 M FMPB = 207.2 g/mol EMAR = 107.9 g/mol 1. 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+ ?
