Chlorine Facts Chlorine has been used as a chemical warfare agent. Sources: In nature, chlorine is only found in the combined state, most commonly with sodium as NaCl and in carnallite (KMgCl 3 •6H 2 O) and sylvite (KCl). The element is obtained from chlorides by electrolysis or via the action of oxidizing agents. Element Classification: Halogen. Density (g/cc): 1.56 (@ -33.6 °C).

- Others. Chlorine is present in food and our body almost entirely in the form of chloride. Chloride is important in maintaining water balance, and is an essential component of gastric juice. We get our supplies of chlorine from food mainly in the form of sodium chloride (salt).

- Chlorine is present in most disinfected drinking-water at concentrations of 0.2–1 mg/litre (3). Cake flour bleached with chlorine contains chloride at levels in the range 1.3–1.9 g/kg. Unbleached flour may contain small amounts of chlorite (400–500 mg/kg) (8). items either bleached or disinfected with it.

- The presence of free chlorine (also known as chlorine residual, free chlorine residual, residual chlorine) in drinking water indicates that: 1) a sufficient amount of chlorine was added initially to the water to inactivate the bacteria and some viruses that cause diarrheal disease; and, 2) the water is protected from recontamination during storage.

What Chemical Compounds Does the Human Body Consist of? Chlorine (0.15%) is usually found in the body as a negative ion, called chloride. This electrolyte is important for maintaining a normal balance of fluids. Magnesium (0.05%) plays an important role in the structure of the skeleton and muscles.

- Nearly all chlorine in the Earth's crust occurs as chloride in various ionic compounds, including table salt. It is the second most abundant halogen and 21st most abundant chemical element in Earth's crust.6 Cl is produced in the atmosphere by spallation of 36 Ar by interactions with cosmic ray protons. In the subsurface environment, 36 Cl is generated primarily as a result of neutron capture by 35 Cl or muon capture by 40 Ca. 36 Cl decays to 36 S and to 36 Ar, with a combined half-life of 308,000 years.

- How is chlorine produced? How is chlorine produced? Chlorine is produced by passing an electric current through a solution of brine (common salt dissolved in water). This process is called electrolysis. The chemical term for salt is sodium chloride (NaCl). Essential co-products are caustic soda (sodium hydroxide or NaOH) and hydrogen (H2).

CHLORINE Chlorine is a member of the halogen family. Halogens are the elements that make up Group 17 (VIIA) of the periodic table, a chart that shows how elements are related to one another. They include fluorine, bromine, iodine, and astatine. Chlorine is highly reactive, ranking only below fluorine in its chemical activity.hlorine, in one form or another, is added to most swimming pools, spas, and public water supplies because it kills bacteria that cause disease. Many people also use chlorine to bleach their clothes. Large paper and pulp mills use chlorine to bleach their products.

Chemical properties An example: chlorine has an atomic number of 17, which basically means that all chlorine atoms contain 17 protons within their core. There are two isotopes. Three-quarters of the chlorine atoms found in nature contain 18 neutrons and one quarter contains 20 neutrons.

Humphry Davy Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who called it dephlogisticated marine acid (see phlogiston theory) and mistakenly thought it contained oxygen. Davy showed that the acid of Scheele's substance, called at the time oxymuriatic acid, contained no oxygen.

- Theconcentrations of hypochlorous acid and the hypochlorite ion are approximately equal at pH7.5 and 25 °C. Chlorine can react with ammonia or amines in water to form chloramines(4,5). ANALYTICAL METHODS A colorimetric method can be used to determine free chlorine in water at concentrations of0.1–10 mg/litre. Other methods allow for the determination of free chlorine, chloramines,other chlorine species, and total available chlorine, and are suitable for total chlorineconcentrations up to 5 mg/litre.

What is chlorine used for? Chlorine is used worldwide to supplies as the ultimate defence against waterborne microbiological infection. Modern day cholera epidemics in Peru, Africa and other regions but also after natural catastrophes like earth quakes or tsunamis exemplify the devastating consequences of contaminated water and poor sanitation.

Chlorine in Nature Chlorine-based compounds are made by marine organisms (sponges, corals, sea slugs, jellyfish and seaweeds), plants, seeds, fungi, lichens, bacteria, freshwater algae and insects. Seaweeds produce at least 400 organohalogens, and certain phytoplankton and seaweeds produce chlorinated metabolites tentatively identified as trichloroethylene and perchloroethylene, compounds well known as chlorinated solvents.

- Chlorine is not found uncombined in nature. Halite (sodium chloride or ‘common salt’) is the main mineral that is mined for chlorine. Sodium chloride is a very soluble salt that has been leached into the oceans over the lifetime of the Earth.

- Very little chlorine exists naturally in the atmosphere. But it turns out that CFCs are an excellent way of introducing chlorine into the ozone layer. The ultraviolet radiation at this altitude breaks down CFCs, freeing the chlorine. Under the proper conditions, this chlorine has the potential to destroy large amounts of ozone.

- The boiling point at standard pressure is around −34 ˚C, but it liquefies at room temperature at 740 kPa (107 psi). Elemental chlorine is yellow-green, but the chloride ion, in common with other halide ions, has no color in either minerals or solutions (example, table salt).

Total Chlorine Chlorine that is present in water consists of two forms: combined and free. The latter performs the job of oxidizing contaminants and killing bacteria. When chlorine is added to water, it is added as free chlorine. Total chlorine is the sum of both free and combined chlorine. When free chlorine comes into contact with various forms of contaminants, the chlorine is transformed to combined chlorine, also known as chloramines.
