Standard Reduction Potentials Tabulated
Captions available
The idea
A standard reduction potential is a half-reaction's potential written as a reduction, measured against the standard hydrogen electrode, tabulated for lookup and combination.
In practice
Cu²⁺ + 2 e⁻ → Cu carries a standard reduction potential of +0.34 V, a fixed reference value.
Where people slip
A tabulated potential describes the reduction as written — reversing it flips the sign, not the magnitude.
