A voltaic cell is constructed with an Ag/Ag half-cell and a Ni/Ni2 half-cell. a. (2 pts) Which metal will serve as the anode and which as the cathode? Justify your answer quantitatively. b. (2 pts) Write a cell reaction for this cell. Write the half-reactions and label them as oxidation and reduction. c. (2 pts) Write the line notation for this cell. d. (2 pts) Determine the standard cell potential. e. (2 pts) If [Ag'] = 0.001 M and [Ni2] 0.01 M, determine the cell potential. E (V) Half reaction E°(V)
Ag+ +e ---> Ag 0.80 Ni2+2e- ----> Ni -0.25
