Considering the given Reduction Potentials:as Ag? (aq) + e‾ (1 electron) Ag (s) E°= + 0.800 Volts;Ni²? (aq) + 2 e‾ (2 electrons) Ni (s) E°= - 0.250 Volts; Cd²? (aq) + 2 e‾ (2 electrons) Cd (s) E°= - 0.400 Volts
Using the given reduction potential determine what is the voltage for these given electrochemical cell as Ni (s) | Ni²? (0.08M) || Cd²? (0.02M) | Cd (s) ?
