Facts about Chlorine
At ordinary temperatures and pressures, pure chlorine is a highly reactive, poisonous gas with a greenish-yellow color and an unpleasant odor.
The electrolytic process generates chlorine in the anode compartment and hydrogen and sodium hydroxide in the cathode compartment.
Chlorine, its ions, and its compounds are widely used in the manufacture of many products, including paper, bleach, antiseptics, dyestuffs, pesticides, paints, solvents, plastics, medicines, and textiles.
Chlorine (chemical symbol Cl, atomic number 17) is a nonmetal that belongs to a group of chemical elements known as halogens.
Chlorine also forms compounds in which it is covalently bound to various nonmetals.
Chlorine has nine isotopes, with atomic mass numbers ranging from 32 to 40.
The diaphragm prevents the chlorine (which forms at the anode) and the sodium hydroxide (which forms at the cathode) from re-mixing.
Rather, famines are brought on by an accumulation of events and policies that carry both “natural” and “artificial” characteristics.
The first electrolytic method of producing chlorine on an industrial scale involved the use of a mercury cell.
One liter of water dissolves 3.10 liters of gaseous chlorine at ten °C, but the same amount of water dissolves only 1.77 liters chlorine gas at 30 °C.
Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who observed the greenish-yellow gas when experimenting with seawater.
When an electrical current was applied, chlorine was released at the anodes and sodium dissolved in the mercury to form an amalgam.
Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides. About 20% of chlorine produced is used to make PVC.
Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. 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.
Chlorine is the chemical most often used to keep swimming pools and Jacuzzis free of bacteria that can be hazardous to humans. ... The chlorine solution you pour into the water breaks down into many different chemicals, including hypochlorous acid (HOCl) and hypochlorite ion (OCl-).

Chlorine can be found in abundance in both the Earth's crust and in ocean water. In the ocean, chlorine is found as part of the compound sodium chloride (NaCl), also known as table salt. In the Earth's crust, the most common minerals containing chlorine include halite (NaCl), carnallite, and sylvite (KCl).
Chlorine has been in use for thousands of years in other forms, but it wasn't named until 1810 by Sir Humphry Davy. Only fluorine is a lighter halogen than chlorine. It is the second most common halogen on Earth. The element itself is the 21st most common element, at about 170 parts per million.
Chlorine is used in pool water because it kills bacteria and germs, oxidizes organic debris from perspiration and body oils, and fights algae. ... And among adults, exposure to chlorine in pools has been linked to bladder and rectal cancer and increased risk for coronary heart disease.Feb 2, 2013
Chlorine: historical information. Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite (manganese dioxide, MnO2) with hydrochloric acid (HCl, then known as muriatic acid). Scheele thought the resulting gas contained oxygen.
Chlorine can be manufactured by electrolysis of a sodium chloride solution (brine). The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.
Origin of name: from the Greek word "chloros" meaning "pale green". Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite (manganese dioxide, MnO2) with hydrochloric acid (HCl, then known as muriatic acid).
