The standard reduction potential, also known as E°red, is a measure of the tendency of a species to gain electrons and be reduced. It represents the voltage associated with a half-reaction under standard conditions (1 M concentration, 1 atm pressure, 298 K temperature).

Oxidation Potential: The oxidation potential is the opposite of the reduction potential and represents the tendency of a species to lose electrons and be oxidized.
Standard Hydrogen Electrode (SHE): The SHE is used as the reference electrode in determining standard reduction potentials. Its reduction potential is defined as zero.
The Nernst equation relates the concentration of reactants and products to the cell potential under non-standard conditions. It allows for calculations involving non-standard concentrations or temperatures.
