If an electrochemical cell is constructed in which the cathode is copper metal immersed in a 1 M Cu²⁺ solution and the anode is zinc metal immersed in a 1 M Zn²⁺ solution, what is the potential difference between the two compartments?

The potential difference can be calculated using the standard electrode potentials (E°) for the half-reactions. For Cu^2+/Cu, E° = +0.34 V, and for Zn^2+/Zn, E° = -0.76 V. The overall cell potential (E°_cell) is calculated as E°_cathode - E°_anode, which gives +0.34 V - (-0.76 V) = +1.10 V.
