Consider the cell potentials
WebSep 19, 2024 · Standard Electrode Potentials. To measure the potential of the Cu/Cu 2 + couple, we can construct a galvanic cell analogous to the one shown in Figure \(\PageIndex{3}\) but containing a Cu/Cu 2 + couple in the sample compartment instead of Zn/Zn 2 +.When we close the circuit this time, the measured potential for the cell is … WebSo Ecell is cathode - anode, but only if you're using reduction potentials since most potential tables give the potentials of the reduction reactions. So if you did this using the …
