Discovered in 1774 by Scheele, who thought it contained oxygen; named in 1810 by Davy, who insisted it was an element.In nature it is found in the combined state only, chiefly with sodium as common salt (NaCl), carnallite (KMgCl3 · 6H2O), and sylvite (KCl). It is amember 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 only1.77 volumes. Chlorine is widely used in making many everyday products. It is used for producing safe drinking water the world over. Even the smallestwater supplies are now usually chlorinated. It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products,medicines, antiseptics, insecticides, foodstuffs, solvents, paints, plastics, and many other consumer products. Most of the chlorine produced is usedin the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufactureof chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. Organic chemistry demands much from chlorine, both as an oxidizingagent and in substitution, since it often brings desired properties in an organic compound when substituted for hydrogen, as in one form of syntheticrubber. Chlorine is a respiratory irritant. The gas irritates the mucous membranes and the liquid burns the skin. As little as 3.5 ppm can be detectedas an odor, and 1000 ppm is likely to be fatal after a few deep breaths. It was used as a war gas in 1915. Natural chlorine contains two isotopes. Sixteenother isotopes and isomers are known. 1


•[used] in drinking water and swimming pools because chlorine is used to disinfect water...Soon after the war [World War I], however, chlorine became the premier disinfectant, controlling deadly diseases such as typhoid fever that were being spread by polluted drinking water." 2
•received notoreity during World War I when it was used as a war gas." 3
•Its greatest commercial use, however, is in the preparation of chlorinated organic compounds, including plastics such as polyvinyl chloride (PVC), for bottles and packaging film." 4
•One of the most important uses for chlorine is as a bleaching agent, especially for cotton cloth...Moist chlorine is a good disinfectant, because it reacts as an oxidizing agent with protein material and kills microscopic organisms, including disease germs...Chlorine is also added to city water to kill germs. Swimming pools are kept sanitary by means of chlorine. A little chlorine added to the discharge from sewage disposal plants renders it harmless...Chlorine is used for paper pulp bleaching, water purification, textile bleaching, de-tinning and de-zincing, chlorinating and for making chlorinated hydrocarbons. Other important uses include the manufacture of carbon tetrachloride...chloroform...sulfur chloride...and many organic compounds used in dyes and medicines...Chlorine is also used for treating petroleum to make many non-inflammable materials used as solvents and cleaning fluids. Some processes for the extraction of metals from ores use chlorine." 5
•used to produce many commercially important products. Tremendous amounts of it are used in extractive metallurgy and in chlorinating hydrocarbons to produce a variety of compounds (such as polyvinyl chloride, a plastic). Chlorine is present as Cl2, NaClO, Ca(ClO)2, or Ca(ClO)Cl in household bleaches as well as bleaches for wood pulp and textiles. Under carefully controlled conditions, Cl2 is used to kill bacteria in public water supplies." 6
