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. ).
