Study Notes
Redox Couples and Electrode Potential
- A redox couple consists of both oxidized and reduced forms of a substance involved in half-reactions.
- Oxidation half-reaction refers to the loss of electrons, while reduction half-reaction refers to the gain of electrons.
- Electrode potential indicates the tendency of an electrode to either lose electrons (oxidation) or gain electrons (reduction).
- Standard electrode potential is defined when the concentration of each species in the electrode reaction is at unity (1 M) and at a temperature of 298 K.
