Other chlorine compounds include: chloroform (CHCl 3), carbon tetrachloride (CCl 4), potassium chloride (KCl), lithium chloride (LiCl), magnesium chloride (MgCl 2) and chlorine dioxide (ClO 2).Ĭhlorine is a very dangerous material. Hydrogen chloride, when mixed with water (H 2O), forms hydrochloric acid, a strong and commercially important acid. Sodium chloride, commonly known as table salt, is used to season food and in some industrial processes. Two of the most familiar chlorine compounds are sodium chloride (NaCl) and hydrogen chloride (HCl). ![]() Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints. Today, most chlorine is produced through the electrolysis of aqueous sodium chloride (NaCl).Ĭhlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Although Scheele thought the gas produced in his experiment contained oxygen, Sir Humphry Davy proved in 1810 that it was actually a distinct element. Chlorine was first produced by Carl Wilhelm Scheele, a Swedish chemist, when he combined the mineral pyrolusite (MnO 2) with hydrochloric acid (HCl) in 1774. ![]() Since it combines directly with nearly every element, chlorine is never found free in nature. ![]()
