WebJul 20, 2024 · An oxidizing and reducing agent which appear on opposite sides of a half-equation constitute a redox couple. Redox couples are analogous to conjugate acid-base pairs and behave in much the same way. WebJun 24, 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 …
