The standard potential of the AgCl/Ag, Cl- electrode can be calculated using the given potentials of the Cu2+/Cu and the overall cell. The overall cell potential is the difference between the cathode and anode potentials. Given that the Cu2+/Cu potential is +0.34 V and the overall cell potential is +0.12 V, the potential of the AgCl/Ag, Cl- electrode can be found by rearranging the cell potential equation: E(cell) = E(cathode) - E(anode). Here, E(cell) = +0.12 V and E(cathode) = E(Cu2+/Cu) = +0.34 V. Solving for E(anode), which is the potential of the AgCl/Ag, Cl- electrode, gives E(anode) = E(cathode) - E(cell) = +0.34 V - +0.12 V = +0.22 V.

The Standard Potential of the Cu2+/Cu Electrode Is +0

The Standard Potential of the Cu²⁺/Cu Electrode Is +0
