WebFor a silver-silver chloride electrode, the following potentials are observed: E.=0.222 VE(saturated KC1)=0.197 V E* = 0.222 V E(saturated KCI) = 0.197 V From these potentials, find the activity of CI-CI- in saturated KCLKCI. Calculate EE for a calomel electrode saturated with KCI,KCI, given that E E for the calomel electrode is 0.268 V.0.268 V. WebTHE NERNST EQUATION We know experimentally that the potential of a single electrode or half-cell varies with the concentration of ions in the cell. In 1889 Walter Nernst derived a mathematical relationship which enable us to calculate the half-cell potential, E, from the standard electrode potential, E°, and the temperature of the cell.
