Where is chlorine found and how is it obtained?
Identified as an element by Sir Humphry Davy in 1810. Occurrence: Found in nature dissolved in salts in seawater and in the deposits of salt mines. Today, most chlorine is produced through the electrolysis of aqueous sodium chloride. Appearance: Yellowish-green, dense, sharp-smelling gas.
Where is chlorine obtained?
Chlorine is obtained by the electrolysis of sodium chloride solutions. Along with sodium, chlorine is abundant in the oceans. Chlorine is present in small amounts in many minerals. The most common chlorine-bearing mineral is, of course, halite (sodium chloride).
How is chlorine obtained and separated?
Chlorine was the first halogen to be separated and recognized as an element. It was named in 1811 by Humphry Davy from a Greek term for its greenish yellow color. Chlorine gas is produced at one electrode. The chlorine must be separated by a membrane from the other electrode, which produces sodium hydroxide.
How was chlorine first obtained?
This element was first isolated in 1774 by the Swiss-German chemist Carl Wilhelm Scheele, by reacting hydrochloric acid with manganese (IV) oxide. But he failed to realise his achievement, mistakenly believing it also contained oxygen. It was Davy in 1810 who finally concluded that Scheele had made elemental chlorine.
Is chlorine CI or Cl?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature….Chlorine.

What is chlorine a byproduct of?
Chlorine, along with its important by-product, sodium hydroxide, is produced from the readily available starting material, rock salt (sodium chloride). It is well known for its use in sterilizing drinking water and in particular swimming pool water.
How is cl2 made?
Most chlorine is manufactured electrolytically by the diaphragm, membrane, or mercury cell process. In each process, a salt solution (sodium or potassium chloride) is electrolyzed by the action of direct electric current which converts chloride ions to elemental chlorine….Chlorine Manufacture.

Is chlorine Cl or CI?
How is chlorine found in nature?
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).
What is chlorine made from?
Why is chlorine gas green?
The halogens darken in colour as the group is descended: thus, while fluorine is a pale yellow gas, chlorine is distinctly yellow-green. This trend occurs because the wavelengths of visible light absorbed by the halogens increase down the group.
How can you obtain chlorine?
Chlorine is obtained by the electrolysis of sodium chloride solutions. Along with sodium, chlorine is abundant in the oceans. Chlorine is present in small amounts in many minerals.
What are common uses of chlorine?
Here are some of the common uses of chlorine in the world today. Uses of Chlorine. Chlorine is used (generally a particular compound of chlorine) to kill bacteria in drinking water and swimming pools. It is also used in disinfectants and bleach for the same reason. Chlorine is very effect against e coli bacteria .
How is chlorine gas commercially prepared?
Commercially, chlorine is prepared by the electrolysis of aqueous sodium chloride obtained from seawater or salt deposits. Another process for the production of chlorine is the Chloralkali Process.
How is chlorine gas made?
The simplest chlorine compound is hydrogen chloride, HCl, a major chemical in industry as well as in the laboratory, both as a gas and dissolved in water as hydrochloric acid. It is often produced by burning hydrogen gas in chlorine gas, or as a byproduct of chlorinating hydrocarbons.
