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".
Electrochemistry also has important applications in the food industry, like the assessment of food/package interactions, [36] the analysis of milk composition, [37] the characterization and the determination of the freezing end-point of ice-cream mixes, or the determination of free acidity in olive oil.
The electrochemical equivalent of a substance is the mass of the substance deposited to one of the electrodes when a current of 1 ampere is passed for 1 second, i.e. a quantity of electricity of one coulomb is passed.
The Handbook of Electrochemistry, edited by Cynthia Zoski, is a sourcebook containing a wide range of electrochemical information.It provides details of experimental considerations, typical calculations, and illustrates many of the possibilities open to electrochemical experimentators.
Example of a reduction–oxidation reaction between sodium and chlorine, with the OIL RIG mnemonic [1]. Electron transfer (ET) occurs when an electron relocates from an atom, ion, or molecule, to another such chemical entity.
They are a class of electrodes named pseudo-reference electrodes because they do not maintain a constant potential but vary predictably with conditions. If the conditions are known, the potential can be calculated and the electrode can be used as a reference.
