redox potential

redox potential (EH) A scale of values, measured as electric potential in volts, indicating the ability of a substance or solution to cause reduction or oxidation reactions under non-standard conditions. The term is sometimes used interchangeably with the term oxidation potential, but in either case the symbol Eθ would refer to standard conditions, while EH signifies non-standard conditions, usually processes in natural systems such as sea water or soils. The higher the value of EH, the more oxidizing the conditions. The redox potential is important in weathering in terms of oxidation and reduction; if the environment will accept electrons it can precipitate Fe(OH)3, if not the Fe2+ ions will remain in solution. Values in natural environments are closely linked, and vary, with changes in pH.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

American Psychological Association

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

redox potential

redox potential A scale that indicates the reduction (addition of electrons) and oxidation (removal of electrons) for a given material. The position on the scale is expressed as an electric potential in millivolts, normally in the range 0–1300 or 0–1400 mV. The pH of the sample must be known since this can alter the reading.
