The Element: Chlorine Essay -- essays research papers

The Element centilitreGeneral InformationWe researched the chemical element cognise as centilitre. centiliter hasan atomic number of 17 and an atomic angle of 35.453. It has avalence number of 3. The element has 3 energy levels. Chlorine existsas a greenish-yellow gas at normal temperatures and pressures. Chlorineis sustain in reactivity only to fluorine among the halogen elements.Chlorine is a nonmetal. It is estimated that 0.045% of the primer coatscrust and 1.9% of sea water ar atomic number 17. Chlorine combines withmetals and nonmetals and original materials to form hundreds ofchlorine compounds. Chlorine is about 2.5 times as duncical as air andmoderately soluble in water, forming a macabre yellowish green solution.Chlorine is so reactive that it never occurs secrete in nature.Chemical PropertiesChlorine is in the halogen family, and like all the oppositehalogen elements chlorine has a strong tendency to gain one electronand become a chloride ion. Chlorine readily reacts with metals to formchlorides, most of which argon soluble in water. Chlorine also reactsdirectly with many nonmetals much(prenominal) as sulfur, phosphorus, and otherhalogens. Chlorine can support combustion if a candle were to be throwninto a vessel of chlorine, it would continue to burn, let go dense,black clouds of smoke, The chlorine combines with hydrogen of theparaffin, forming hydrogen chloride, and uncombined carbon is unexpended inthe form of soot. Soot is black residue from fuel. Chlorine replaces iodin and bromine from their salts. modify chlorine is somewhat inert or non able to move, but moist chlorine unites directly with most of theelements. memoirChlorine was discovered in 1774 by Karl Scheele. Humphry Davyproved that chlorine was an element. encompassing production began 100years later. During the 20th Century. The amount of Chlorine use wasconsidered a measure of industrial growth. In, 1975 chlorineproductions ranked seventh on the list of largest-volu me chemicalsproduced in the United States. The importance of chlorine has changedas refreshed uses remove been added. In 1925 paper and pulp used over one-one-half . The chlorine made and chemical products only 10%. By the 1960spaper and pulp use accounted for only 15-17% and the chemical usesincreased to 75-80%. Peoples uses have contributed to the growth oflarge cities, and new textiles, plastics, paints, and miscellaneous useshave raise... ...h chlorine. At the beseech cathode or negatively charged electrode,sodium ions are reduced to sodium metal, which reacts immediately withwater to form sodium hydroxide.Another method of preparing chlorine is by the electrolysis ofmolten salt. This accomplish is used specifically to produce sodium, andthe chlorine is a commercial by product. When large quantities ofwaste hydrochloric and are available. Chlorine may be recovered byoxidation of the acid. This method has the favor of convertinggreat quantities of waste acid to useful subst ances.No matter what process is used to prepare chlorine, the gasmust be well dried. Dry chlorine is much less corrosive than moistchlorine gas. In the laboratory chlorine may be prepared by thawmanganese oxide with hydrochloric acid.ConclusionIn conclusion chlorine is a really wonderful element. Chlorine hashundreds of compounds. If we did not have these compounds we wouldnot have rinse water, we would have an insect problem, we could notmake many important compounds that are used in medicine, and some ofthe battles in World War I might have been lost if it were not forchlorine. Our world would not be the same if not for chlorine.
