Everything about The Chloride totally explained
The
chloride ion is formed when the
element chlorine picks up one
electron to form an
anion (negatively-charged ion)
Cl−. The
salts of
hydrochloric acid HCl contain chloride ions and can also be called
chlorides. An example is table salt, which is
sodium chloride with the
chemical formula NaCl. In
water, it dissolves into Na
+ and Cl
− ions.
The word
chloride can also refer to a
chemical compound in which one or more chlorine
atoms are
covalently bonded in the
molecule. This means that chlorides can be either
inorganic or
organic compounds. The simplest example of an inorganic covalently-bonded chloride is
hydrogen chloride, HCl. A simple example of an organic covalently-bonded (an
organochloride) chloride is
chloromethane (CH
3Cl), often called methyl chloride.
Other examples of inorganic covalently-bonded chlorides that are used as
reactants are:
Human health
Chloride is a chemical the human body needs for metabolism (the process of turning the food you eat into energy). It also helps keep the body's acid-base balance. The amount of chloride in the blood is carefully controlled by the kidneys.

Chloride ions have important
physiological roles. For instance, in the
central nervous system, the inhibitory action of
glycine and some of the action of
GABA relies on the entry of Cl
− into specific neurons. Also, the
chloride-bicarbonate exchanger biological transport
protein relies on the chloride ion to increase the
blood's capacity of
carbon dioxide, in the form of the
bicarbonate ion.
The normal
blood reference range of chloride for adults in most labs is 95 to 105 milliequivalents (mEq) per liter. The normal range may vary slightly from lab to lab. Normal ranges are usually shown next to your results in the lab report.
The North American
Dietary Reference Intake recommends a daily intake of between 2300 and 3600 mg/day for 25-year-old males.
Other applications
Chloride is also a useful and reliable chemical indicator of river / groundwater fecal contamination, as chloride is a non-reactive solute and ubiquitous to sewage.
