Physical and chemical properties. Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at ?34 °C (?29 °F). It has a choking smell, and inhalation causes suffocation, constriction of the chest, tightness in the throat, and—after severe exposure— edema (filling with fluid) of the lungs. Apr 04, · Chlorine is one of the most commonly manufactured chemicals in the United States. Its most important use is as a bleach in the manufacture of paper and cloth, but it is also used to make pesticides (insect killers), rubber, and solvents. Chlorine is used in drinking water and swimming pool water to kill harmful bacteria. Chlorine has a variety of uses. It is used to disinfect water and is part of the sanitation process for sewage and industrial waste. During the production of paper and cloth, chlorine is used as a bleaching agent. It is also used in cleaning products, including household bleach which is chlorine dissolved in water. Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It has a choking smell, and inhalation causes suffocation, constriction of the chest, tightness in the throat, and—after severe exposure— edema filling with fluid of the lungs. As little as one part per thousand in air causes death within a few minutes, but less than one part per million may be tolerated. Chlorine was the first gas used in chemical warfare in World War I. The gas is easily liquefied by cooling or by pressures of a few atmospheres at ordinary temperature. Chlorine has a high electronegativity and a high electron affinity , the latter being even slightly higher than that of fluorine. In the presence of charcoal , the combination of chlorine and hydrogen takes place rapidly but without explosion in the dark. A jet of hydrogen will burn in chlorine with a silvery flame. Its high affinity for hydrogen allows chlorine to react with many compounds containing hydrogen. Chlorine reacts with hydrocarbons , for example, substituting chlorine atoms for the hydrogen atoms successively. If the hydrocarbon is unsaturated, however, chlorine atoms readily add to the double or triple bond. Chlorine molecules are composed of two atoms Cl 2. Chlorine combines with almost all the elements, except for the lighter noble gases , to give chlorides; those of most metals are ionic crystals , whereas those of the semimetals and nonmetals are predominantly molecular. The products of reaction with chlorine usually are chlorides with high oxidation numbers , such as iron trichloride FeCl 3 , tin tetrachloride SnCl 4 , or antimony pentachloride SbCl 5 , but it should be noted that the chloride of highest oxidation number of a particular element is frequently in a lower oxidation state than the fluoride with the highest oxidation number. Thus, vanadium forms a pentafluoride, whereas the pentachloride is unknown, and sulfur gives a hexafluoride but no hexachloride. With sulfur, even the tetrachloride is unstable. Five oxides—chlorine monoxide Cl 2 O , chlorine dioxide ClO 2 , chlorine perchlorate Cl 2 O 4 , dichlorine hexoxide Cl 2 O 6 , and dichlorine heptoxide Cl 2 O 7 —all highly reactive and unstable, have been indirectly synthesized. Chlorine can undergo addition or substitution reactions with organic compounds. Chlorine displaces the heavier, less electronegative halogens , bromine and iodine , from compounds. The displacement of bromides, for example, occurs according to the following equation:. Furthermore, it converts several oxides into chlorides. An example is the conversion of iron trioxide to the corresponding chloride:. This hydrate is characterized by a structure that is more open than that of ice; the unit cell contains 46 molecules of water and 6 cavities suitable for the chlorine molecules. When the hydrate stands, disproportionation takes place; that is, one chlorine atom in the molecule is oxidized, and the other is reduced. At the same time, the solution becomes acidic, as shown in the following equation:. Chlorine water loses its efficiency as an oxidizing agent on standing, because hypochlorous acid gradually decomposes. The reaction of chlorine with alkaline solutions yields salts of oxyacids. The first ionization energy of chlorine is high. Although ions in positive oxidation states are not very stable, high oxidation numbers are stabilized by coordination, mainly with oxygen and fluorine. Additional Info.
