Many of chloro-organic compounds can be found in biomolecules, and the majority of chloro-hydrocarbons such as chloromethane can be found in the atmosphere due to the biological decomposition of other organic molecules.Ĭhorine does not only help in keeping the water clean, but it also helps in wastewater treatment. Chlorine goes under free-radical electrophilic substitution with alkanes and aryl alkanes. ![]() In saturated hydrocarbons, chlorine replaces hydrogen, either entirely or partially, to form chlorinated hydrocarbons and hydrogen chloride. It generally goes under substitution or addition reactions with hydrocarbons. It plays a key role in the manufacture of thousands of products that we depend on every day, including volleyballs, computers, cars, pool chemicals, medicines, and cosmetics.Ĭhlorine usually forms covalent bonds with carbon. It is a necessary ingredient in the diets of people and animals. The gas is captured and cooled down so that it can be liquefied. Chemical engineers design systems to make chlorine gas bubble out of salty-electrified water. ![]() Electricity is used to electro-chemically split NaCl, releasing Cl for its many chemical uses. A large amount of chlorine is produced with the help of mineral salts found in the ocean water. Common Salt (NaCl)Ĭommon salt is the most abundant repository of chlorine on earth. However, hydrochloric acid is more acidic than hydrofluoric acid due to the presence of stronger hydrogen bonding in HF that does not break easily, and hence, does not form ions. It is also used to process sugar and make gelatin. Hydrochloric acid is also used in the production of batteries, photoflash bulbs, and fireworks. ![]() It is used in the metal industry to process steel, the material of choice for suspension bridges, cars, and trucks. Hydrochloric acid is also produced naturally by our stomach to digest food. In fact, it was first used in 1847 as a germicide to prevent the spread of “childbed fever” in the maternity wards of Vienna General Hospital in Austria.Ĭhlorine has 25 isotopes with mass numbers ranging from _ + HCl Chlorine’s powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Chlorine disinfectants destroy and deactivate a wide range of dangerous germs in homes, hospitals, swimming pools, hotels, restaurants, and other public places. In 1810, he suggested the name “chloric gas” or “chlorine.” Since then, it has become one of the most effective and economical germ-killers. Davy gave the element its name based on the Greek word “khloros” in reference to its greenish-yellow color. Until an English chemist, Sir Humphrey Davy, recognized that the gas produced in the reaction was elemental chlorine, people were convinced that the gas was a compound of oxygen. At the time, he had no idea that he had just discovered chlorine. In 1774, Swedish pharmacist Carl Wilhem Scheele released a few drops of hydrochloric acid onto a piece of manganese dioxide and observed a greenish-yellow gas evolving from that chunk of manganese dioxide.
