Final answer:
The standard potential of the galvanic cell is 1.0V.
Step-by-step explanation:
The standard potential of a galvanic cell can be calculated using the equation: Ecell = E(cathode) - E(anode). In this case, the cathode is Cu and the anode is Cu. From the given information, the standard reduction potential of the Cu/Cu²+ half-reaction is 0V. Since the standard cell potential is 1.0V, the standard reduction potential of the Cu²+/Cu half-reaction can be calculated by subtracting the standard potential of the Cu/Cu²+ half-reaction from the standard cell potential:
E(Cu²+/Cu) = Ecell - E(Cu/Cu²+) = 1.0V - 0V = 1.0V.
