To calculate the minimum standard reduction potential that the half-reaction used at the anode of this cell can have, we need to use the equation:


E°cell = E°cathode - E°anode
where E°cell is the standard cell potential, E°cathode is the standard reduction potential of the half-reaction used at the cathode, and E°anode is the standard reduction potential of the half-reaction used at the anode.
We know that the E°cathode is -0.58 V and the E°cell must be at least 1.20 V. Therefore, we can rearrange the equation above to solve for the minimum E°anode:
E°anode = E°cathode - E°cell
E°anode = -0.58 V - (1.20 V)
E°anode = -1.78 V
Therefore, the minimum standard reduction potential that the half-reaction used at the anode of this cell can have is -1.78 V.
Answer: Yes, the minimum standard reduction potential that the half-reaction used at the anode of this cell can have is E° = -1.78 V.
