Standard reduction potential example
Webb16 dec. 2024 · The reduction potentials are a special case of standard reaction enthalpy, because you can transform $\Delta E$ into $\Delta H$ just by calculating with a few … WebbFor example, the measured standard cell potential ( E °) for the Zn/Cu system is 1.10 V, whereas E ° for the corresponding Zn/Co system is 0.51 V. This implies that the potential difference between the Co and Cu electrodes is 1.10 V − 0.51 V = 0.59 V.
