2. Determining standard potentials

2.1 Electrochemical measurements

Given the definition of standard potentials, the most obvious method for determining the standard potential of an Ox/Red couple is to set up the reversible electrochemical cell (29) using all compounds in their standard states. A standard hydrogen electrode is then associated with a second electrode whose equilibrium potential is that of the redox couple with Ox and Red in their standard states. The standard potential EOx/Red ο of the couple is then given by the electromotive...
