Chlorine is a reactive halogen and a yellow-green diatomic gas, Cl₂, under ordinary conditions. It is a strong oxidizing agent and occurs naturally mainly as chloride salts, especially in seawater and evaporite minerals. Chlorine chemistry is central to water disinfection, inorganic chlorides, chlorinated solvents, polymers, and many industrial oxidation and substitution processes. The element has two stable isotopes, ³⁵Cl and ³⁷Cl.
It is a member of the halogen (salt-forming) group of elements and is obtained from chlorides by the action of oxidizing agents and more often by electrolysis; it is a greenish-yellow gas, combining directly with nearly all elements. At 10°C one volume of water dissolves 3.10 volumes of chlorine, at 30°C only 1.77 volumes.
The name derives from the Greek chloros for "pale green" or "greenish yellow" colour of the element. It was discovered by the Swedish pharmacist and chemist Carl-Wilhelm Scheele in 1774. In 1810, the English chemist Humphry Davy proved it was an element.
Since it combines directly with nearly every element, chlorine is never found free in nature. Chlorine was first produced by Carl Wilhelm Scheele, a Swedish chemist, when he combined the mineral pyrolusite (MnO2) with hydrochloric acid (HCl) in 1774. Although Scheele thought the gas produced in his experiment contained oxygen, Sir Humphry Davy proved in 1810 that it was actually a distinct element. Today, most chlorine is produced through the electrolysis of aqueous sodium chloride (NaCl).
From the Greek word chloro, greenish yellow. Discovered in 1774 by Scheele, who thought it contained oxygen. Chlorine was named in 1810 by Davy, who insisted it was an element.
Pure chlorine is a dense yellow-green gas with a sharp, irritating odor. It condenses to an amber liquid under pressure or cooling and freezes to a pale solid. The gas is visibly colored even at moderate concentrations in laboratory vessels.
Elemental chlorine, Cl₂, is used chiefly as a chemical intermediate rather than as an end product. Major uses include production of vinyl chloride for polyvinyl chloride, manufacture of chlorinated solvents and intermediates, bleaching of some pulp and textile streams, and synthesis of inorganic chlorides. Chlorine and hypochlorite solutions are widely used for drinking-water, wastewater, and swimming-pool disinfection. Hydrochloric acid, HCl, made directly or as a by-product, is also an important industrial reagent.
Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.
Two of the most familiar chlorine compounds are sodium chloride (NaCl) and hydrogen chloride (HCl). Sodium chloride, commonly known as table salt, is used to season food and in some industrial processes. Hydrogen chloride, when mixed with water (H2O), forms hydrochloric acid, a strong and commercially important acid. Other chlorine compounds include: chloroform (CHCl3), carbon tetrachloride (CCl4), potassium chloride (KCl), lithium chloride (LiCl), magnesium chloride (MgCl2) and chlorine dioxide (ClO2).
Chlorine is a very dangerous material. Liquid chlorine burns the skin and gaseous chlorine irritates the mucus membranes. Concentrations of the gas as low as 3.5 parts per million can be detected by smell while concentrations of 1000 parts per million can be fatal after a few deep breaths.
Chlorine is widely used in making many everyday products. It is used for producing safe drinking water the world over. Even the smallest water supplies are now usually chlorinated.
It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products.
Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine.
Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber.
Isotopes in Earth/Planetary Science
Because molecules, atoms, and ions of the stable isotopes of chlorine possess slightly different physical and chemical properties, they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights. There are substantial variations in the isotopic abundances of chlorine in natural terrestrial materials (Fig. IUPAC.17.1). These variations are useful for investigating the origin of substances and studying environmental, hydrological, and geological processes. Chlorine is subject to isotopic fractionation by physical and chemical processes. Variations in isotopic compositions of stable chlorine isotopes provide evidence for ultrafiltration and crystallization of brines and indicate sources of chlorine-bearing contaminants, such as solvents and rocket fuels, in the environment [151] H. G. M. Eggenkamp, R. Kreulen, A. F. Koster Van Groos. Geochim. Cosmochim. Acta59, 5169 (1995)., [152] M. A. Stewart, A. J. Spivack. Rev. Mineral. Geochem.55, 231 (2004)..
Isotopes in Forensic Science and Anthropology
Analyses of chlorine isotopes and other environmental tracers can help to identify whether an environmental contaminant is of anthropogenic origin or naturally occurring. For example, perchlorate (ClO4 -) can be of anthropogenic origin and is also found naturally. Perchlorate is a widespread groundwater contaminant that can interfere with hormone production in the thyroid gland by displacing iodide. Both the stable chlorine isotope-amount ratio n(37Cl)/n(35Cl) and the mole fraction of 36Cl, n(36Cl)/n(Cl), can provide useful information about origins of perchlorate in the environment (Fig. IUPAC.17.2). Such information may be important for legal reasons and for remediation of contaminated areas [152] M. A. Stewart, A. J. Spivack. Rev. Mineral. Geochem.55, 231 (2004)., [153] J. K. Böhlke, N. C. Sturchio, B. Gu, J. Horita, G. M. Brown, W. A. Jackson, J. R. Batista, P. B. Hatzinger. Anal. Chem.77, 7838 (2005)..
Isotopes in Geochronology
Radioactive 36Cl provides a useful tool to determine ages in geology and hydrology. Some radioactive 36Cl is cosmogenic and enters the terrestrial environment in precipitation. Because of its long half-life of 3.01×105 years, the level of 36Cl in aquifers can be measured and used to estimate ages (on the order of 105 to 106 years) of old meteoric groundwater (water that was originally precipitation) [155] F. M. Phillips. “Chlorine-36”, in Environmental Tracers in Subsurface Hydrology, P. G. Cook and A. L. Herczeg (Eds.), Kluwer Academic Publishers, Boston MA (2000)..
Thermonuclear bomb tests in the ocean produced large amounts of 36Cl by neutron reactions with 35Cl in seawater. This was especially prevalent in the late 1950s. Large amounts of this anthropogenic 36Cl were distributed throughout the atmosphere, deposited with precipitation, and incorporated into terrestrial soils and groundwater. This enriched 36Cl has been used as a tracer of meteoric water from that era [156] F. M. Phillips, J. L. Mattick, T. A. Duval, D. Elmore, P. W. Kubik. Water Resour. Res.24, 877 (1988)..
Chlorine commonly forms chloride compounds in the −1 oxidation state, including sodium chloride, NaCl, hydrogen chloride, HCl, and many metal chlorides. It also forms positive oxidation states in oxyanions such as hypochlorite, ClO⁻, chlorite, ClO₂⁻, chlorate, ClO₃⁻, and perchlorate, ClO₄⁻. Important molecular compounds include chlorine dioxide, ClO₂, and phosphorus trichloride, PCl₃. Organic chlorides range from simple chloromethane, CH₃Cl, to complex polymers and pharmaceuticals.
See more information at the Chlorine compound page.
Chlorine, Cl₂, is acutely toxic by inhalation and strongly irritating to eyes, skin, and the respiratory tract. It reacts with moisture in tissues to form acidic and oxidizing species. Concentrated hypochlorite solutions and chlorine dioxide, ClO₂, are hazardous oxidizers, and mixing hypochlorite with acids can release chlorine gas. Many chloride salts are low-hazard at ordinary exposure levels, but toxicity depends strongly on the accompanying cation or organic group.
Chlorine is a respiratory irritant. The gas irritates the mucus membranes and the liquid burns the skin. As little as 3.5 ppm can be detected as an odor, and 1000 ppm is likely to be fatal after a few deep breaths. In fact, chlorine was used as a war gas in 1915.
Chlorine is abundant in the environment mainly as chloride, Cl⁻, dissolved in seawater, brines, soils, and biological fluids. Marine aerosols, evaporite deposits, volcanic gases, and weathering move chlorine through natural cycles. Reactive chlorine compounds are formed naturally in the atmosphere and by organisms, but industrial organochlorines have added persistent pollutants in some settings. Chloride is mobile in water and is not readily removed by ordinary soil adsorption.
Chlorine is produced industrially by electrolysis of brine, usually together with sodium hydroxide, NaOH, and hydrogen, H₂, in the chlor-alkali process. The economics are closely tied to demand for caustic soda and for chlorine-consuming products such as polyvinyl chloride and isocyanates. Because chlorine gas is hazardous to transport, large users are often integrated with production sites or consume it nearby. Recycling is indirect: chloride from wastes may be recovered in salts or converted through industrial processes, but much chlorine ultimately disperses as chloride.
In nature it is found in the combined state only, chiefly with sodium as common salt (NaCl), carnallite, and sylvite.
Chlorine is a moderately abundant cosmic element made mainly in massive stars and supernova-related nucleosynthesis. It is less abundant than neighboring elements such as sulfur and argon. In planetary materials it is strongly lithophile and volatile relative to many rock-forming elements, occurring as chlorides, brines, and volcanic gases. Chlorine-bearing salts have been detected or inferred on several planetary bodies.
- Chlorine gas was used as a chemical weapon in the First World War.
- Natural chlorine has a stable isotope ratio that is useful in isotope geochemistry.
- Dry chlorine is less corrosive to many metals than moist chlorine.
- Common table salt contains chlorine as chloride, not as elemental Cl₂.
- Perchlorate salts can persist in arid soils and interfere with iodide uptake.
- Chlorine is liquefied commercially for storage and transport under pressure.

Isotopes in Forensic Science and Anthropology
Information on the use of this element's isotopes in forensic science and anthropology.
Analyses of chlorine isotopes and other environmental tracers can help to identify whether an environmental contaminant is of anthropogenic origin or naturally occurring. For example, perchlorate (ClO4 -) can be of anthropogenic origin and is also found naturally. Perchlorate is a widespread groundwater contaminant that can interfere with hormone production in the thyroid gland by displacing iodide. Both the stable chlorine isotope-amount ratio n(37Cl)/n(35Cl) and the mole fraction of 36Cl, n(36Cl)/n(Cl), can provide useful information about origins of perchlorate in the environment (Fig. IUPAC.17.2). Such information may be important for legal reasons and for remediation of contaminated areas [152] M. A. Stewart, A. J. Spivack. Rev. Mineral. Geochem.55, 231 (2004)., [153] J. K. Böhlke, N. C.
