Editing Calomel (section)

==Electrochemistry==
Calomel is used as the interface between metallic mercury and a chloride solution in a [[saturated calomel electrode]], which is used in [[electrochemistry]] to measure [[pH]] and electrical potentials in solutions. In most electrochemical measurements, it is necessary to keep one of the electrodes in an electrochemical cell at a constant potential. This so-called reference electrode allows control of the potential of a working electrode.<ref>{{Citation|last=Kahlert|first=Heike|chapter=Reference Electrodes|date=2010-09-01|chapter-url=https://www.researchgate.net/publication/226760324|isbn=978-3-642-02914-1|publisher=Springer-Verlag Berlin Heidelberg|pages=[https://archive.org/details/electroanalytica0000unse/page/291 291–308]|access-date=2018-07-10|doi=10.1007/978-3-642-02915-8_15|title=Electroanalytical Methods|url=https://archive.org/details/electroanalytica0000unse/page/291}}.
