Webb8 apr. 2024 · As most electrochemical reactions are not performed under standard conditions, it is important to recognise that the concentration has an effect on the redox potential. For a reversible reaction, this relationship is described in the Nernst equation. It assumes that, at a certain potential, both species of the redox couple are in equilibrium. WebbIt is generally performed by applying an initial potential at which no faradaic reaction is occurring, then stepping the potential to a value at which the electrochemical reaction of interest takes place. The solution is usually unstirred and the current is measured throughout the experiment.
