Chlorine
Chlorine is (at room temperature) a greenish-yellow gas that can be
easily liquefied in 5170 Tarr or 6. 8 atmospheres, at 20 C (68 F), and has a
extremely disagreeable scent. Its Aspect Symbol is usually Cl, atomic number is definitely 17, and
atomic mass is thirty-five. 453. Chlorines melting stage is -101 C or 149. eight F. The
boiling point is -34. 05 C or -29. 29 Farreneheit, at 1 atmosphere pressure. Chlorine is a
member of the halogen group. Chlorine was discovered by simply Swedish man of science Karl
Wilhelm in 1784, but this individual first believed it to be a chemical substance, rather than a feature.
In 1810, Sir Humphrey Davy known as it Chlorine, from the Greek word which means
greenish-yellow.
Chlorine is used in bleaching real estate agents, disinfectants, monomers (plastics)
solvents, and insect sprays. It is also employed for bleaching paper pulp and other
organic supplies, preparing bromine, (a toxic element that at space
temperature can be described as dark, reddish-brown), tetraethyl lead, and killing germs in
water, especially in swimming pools and sizzling tubs.
Like every member of the halogen group, chlorine can gain 1
electron and turn into a chloride ion. Chlorine strongly acts with metals to form
generally water-soluble chlorides. Chlorine likewise strongly reacts with nonmetals
such as sulfur, phosphorus, and other halogens. In the event that you where to mix hydrogen and
chlorine gases and keep them in a great dark place, the mix would be secure
but if this were subjected to sunlight, it could cause a strong explosion. If a
burning candle light were put into a closed container of chlorine, it might keep
losing, and it might produce heavy, black, smoke, leaving behind soot. There
happen to be five oxides that chlorine can form: chlorine monoxide, dichloride monoxide
chlorine dioxide, chlorine heptoxide, and chlorine hexoxide. Chlorine can be used in
bleaching agents, disinfectants, monomers (plastics), solvents, and pesticides.
It is additionally used for bleaching paper pulp and other organic and natural materials, organizing
bromine, (a poisonous factor that at room heat is a darker, reddish-brown)
tetraethyl lead, and killing bacteria in water, particularly in swimming pools and
hot tubs.

Additional Information
Chlorine was the first substance used as a toxic gas in World War I actually (1914-
1919), along with gases like tear gas, phosgene (a lung irritant), and mustard
gas. Flame-throwers were also tried out, but at first were thought ineffective
because of their short selection, but when napalm (made from palmitic and napthenic
acids), a sort of heavy, sticky gasoline, was developed, fire throwers had been
quite useful in World War II.
Many Chlorine is made by electrolysis of a sodium solution, using a by-
merchandise of salt hydroxide. Some industrial chlorine is made simply by oxidizing
hydrogen chloride (a colorless, corrosive, non-flammable gas with a going through
suffocating scent. ).
