This gives the SCE a potential of +0.248 V vs. SHE at 20 °C and +0.244 V vs. SHE at 25 °C, [1] but slightly higher when the chloride solution is less than saturated. For example, a 3.5M KCl electrolyte solution has an increased reference potential of +0.250 V vs. SHE at 25°C while a 1 M solution has a +0.283 V potential at the same temperature.
The overall chemical reaction taking place in a cell is made up of two independent half-reactions, which describe chemical changes at the two electrodes. To focus on the reaction at the working electrode , the reference electrode is standardized with constant (buffered or saturated) concentrations of each participant of the redox reaction.
During the early development of electrochemistry, researchers used the normal hydrogen electrode as their standard for zero potential. This was convenient because it could actually be constructed by "[immersing] a platinum electrode into a solution of 1 N strong acid and [bubbling] hydrogen gas through the solution at about 1 atm pressure".

Quote boxes should generally be avoided as they draw attention to the opinion of one source as though Wikipedia endorses it, which may violate the neutral point of view policy. Avoid stand-alone quote sections; use Wikiquote instead. The {} template can be used in Wikipedia articles to indicate there are relevant quotes at Wikiquote.
Natura non facit saltus [1] [2] (Latin for "nature does not make jumps") has been an important principle of natural philosophy.It appears as an axiom in the works of Gottfried Leibniz (New Essays, IV, 16: [2] "la nature ne fait jamais des sauts", "nature never makes jumps"), one of the inventors of the infinitesimal calculus (see Law of Continuity).
