Ĭhlorine reacts with oxygen in air to form chlorine dioxide, a toxic gas.Ĭhlorine readily combines with water to form an acid known as hydrochloric acid. It can also disinfect water by killing most living organisms in it, making it easier to drink safely.Ĭhlorine is a strong oxidizing agent that readily forms compounds with many elementsĬhlorine readily forms compounds with hydrogen to form hydrochloric acid, which is commonly used to clean pools and manufacturing equipment because of its corrosiveness. In industry, chlorine is used as a bleaching agent and as an ingredient in the manufacture of plastics and solvents. Inorganic chemist John Emsley writes in “Nature’s Building Blocks” that “chlorine is one of the most reactive elements known.”Īs an oxidizing agent, it can be used to remove organic material from plant samples for further study under a microscope. The chemical properties of chlorine are similarly versatile, as it combines with most elements to form compounds called chlorides. Density- 2 grams per cm-1 cubed Chemical Properties of Chlorine Element They are commonly used in swimming pools to kill bacteria so that the pool stays clean for longer periods of time without too much cleaning, but care must be taken since they are corrosive.Ĥ. It can turn into liquid at -34 degrees Celsius and solidifies to form white crystals at -101 degrees C. Appearance Chlorine gas has a pale yellow color and is also known as liquefied chlorine or chloride of lime, because it readily forms compounds with almost all other elements. Here are some important physical properties of chlorine element.ġ. Joseph Priestley, an English chemist, later isolated chlorine Physical Properties of Chlorine Element He called the gas “dephlogisticated muriatic acid” because it was produced by heating hydrochloric acid (muriatic acid). The discovery of chlorine relates to when Carl Wilhelm Scheele, a Swedish pharmacist, was working with pyrolusite and noticed a green gas escaping from it. Chlorine gas was first used as a weapon by the French in World War I. Safety measurements while working with ChlorineĬhlorine was discovered by Carl Wilhelm Scheele in 1774, who named it after the Greek word khloros, meaning “greenish-yellow”.Chemical Properties of Chlorine Element.Physical Properties of Chlorine Element.
