Standard electrode potential

In electrochemistry, standard electrode potential E ⊖ {\displaystyle E^{\ominus }} , or E r e d ⊖ {\displaystyle E_{red}^{\ominus }} , is the electrode potential (a measure of the reducing power of any element or compound) which the IUPAC "Gold Book" defines as "the value of the standard emf (electromotive force) of a cell in which molecular hydrogen under standard pressure is oxidized to solvated protons at the left-hand electrode". == Background == The basis for an electrochemical cell, such as the galvanic cell, is always a redox reaction which can be broken down into two half-reactions: oxidation at anode (loss of electron) and reduction at cathode (gain of electron).
