In fact, chlorine was used as a war gas in 1915.Įxposure to chlorine should not exceed 0.5 ppm (8-hour time-weighted average - 40 hour week). 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. Chlorines discovery, interesting facts, and properties - plus informative videos and comprehensive data tables. The gas irritates the mucus membranes and the liquid burns the skin. HandlingĬhlorine is a respiratory irritant. 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. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. 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. Even the smallest water supplies are now usually chlorinated. It is used for producing safe drinking water the world over. UsesĬhlorine is widely used in making many everyday products. At 10☌ one volume of water dissolves 3.10 volumes of chlorine, at 30☌ only 1.77 volumes. 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. In nature it is found in the combined state only, chiefly with sodium as common salt (NaCl), carnallite, and sylvite. Chlorine was named in 1810 by Davy, who insisted it was an element. Discovered in 1774 by Scheele, who thought it contained oxygen. Free Essay: Chlorine The element chlorine is located in the 7th group in the periodic table it is the symbol for CI. This chemical, when used in small doses, has no side effects in large doses, however, it is fatal.ħ, 6, 5, 4, 3, 2, 1, −1 (a strongly acidic oxide)įrom the Greek word chloro, greenish yellow. Up to date, curated data provided by Mathematica s ElementData function from Wolfram Research, Inc. It is used in swimming pools commonly and also making drinking water safe by killing bacteria. Notes on the properties of Chlorine: Density: Density given for Cl at 0° Celsius. Chlorine much like other Halogens has antiseptic properties. ![]() It has the atomic number 17 in the periodic table and belongs in Group 17, the Halogens. ![]() This one is about chlorine - element number 17, an extremely. Chlorine (Cl) exists as a yellow green gas with a pungent smell. Some tree frogs contain a chlorine compound in their skin that is a very powerful pain killer. The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table.
