The chloride ion is the anion negatively charged Cl−.

Chloride ion is formed when the element chlorine gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.

Chloride salts such as sodium chloride are often very soluble in water.

Chloride is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.

Less frequently, chloride terminology is used as part of the name of chemical compounds in which one or more chlorine atoms are covalently bonded: methyl chloride.

It is a structural component of some proteins.

Chloride is one of the essential dietary minerals listed by its element name chlorine.

Most chloride, is filtered by the glomerulus.

Chloride is reabsorbed by both proximal and distal tubules, by both active and passive transport.

Sodium chloride ions tend to link to several cations and in seawater, significantly worsens corrosion of most metals; stainless steels, aluminum and high-alloyed materials.

Increased concentrations of chloride can contribute to the acidification of streams, mobilize radioactive soil metals by ion exchange, and pair reproduction of aquatic plants and animals.

Sodium chloride can change the composition of microbial species at relatively low concentrations.

Chloride can hinder the denitrification process, essential to nitrate removal and the conservation of water quality.

The chlor-alkali industry converts sodium chloride into chlorine and sodium hydroxide, which are used to make many other materials and chemicals.

Table salt, which is sodium chloride with the chemical formula NaCl.

Covalently bonded chlorides are reactive chlorinating reagents that have been used in a laboratory.

Chloride is used in desalination, which involves the energy intensive removal of chloride salts to give potable water.

Chlorides are a constituent of the mud system, and may be an indication of drilling into a high-pressure saltwater formation.

Chloride is a chemical indicator of river/groundwater fecal contamination, as chloride is a non-reactive solute and ubiquitous to sewage & potable water.
