| abstract | - Chlorine was a substance. It was added to satellites orbiting Exis Station. It was also present in the atmospheres of Honoghr and Q'Maere, the latter containing an large poisonous amount.
- Chlorine is a chemical element with symbol Cl and atomic number 17. Chlorine is in the halogen group (17) and is the second lightest halogen following fluorine. The element is a yellow-green gas under standard conditions, where it forms diatomic molecules. Chlorine has the highest electron affinity and the third highest electronegativity of all the reactive elements. For this reason, chlorine is a strong oxidizing agent. Free chlorine is rare on Earth, and is usually a result of direct or indirect oxidation by oxygen. The most common compound of chlorine, sodium chloride (common salt), has been known since ancient times. Around 1630 chlorine gas was first synthesized in a chemical reaction, but not recognized as a fundamentally important substance. Characterization of chlorine gas was made in 1774 by Carl Wilhelm Scheele, who supposed it to be an oxide of a new element. In 1809, chemists suggested that the gas might be a pure element, and this was confirmed by Sir Humphry Davy in 1810, who named it from Ancient Greek: χλωρóς (khlôros) "pale green". 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. Elemental chlorine is commercially produced from brine by electrolysis. The high oxidizing potential of elemental chlorine led commercially to free chlorine's bleaching and disinfectant uses, as well as its many uses of an essential reagent in the chemical industry. Chlorine is used in the manufacture of a wide range of consumer products, about two-thirds of them organic chemicals such as polyvinyl chloride, as well as many intermediates for production of plastics and other end products which do not contain the element. As a common disinfectant, elemental chlorine and chlorine-generating compounds are used more directly in swimming pools to keep them clean and sanitary. In the form of chloride ions, chlorine is necessary to all known species of life. Other types of chlorine compounds are rare in living organisms, and artificially produced chlorinated organics range from inert to toxic. In the upper atmosphere, chlorine-containing organic molecules such as chlorofluorocarbons have been implicated in ozone depletion. Small quantities of elemental chlorine are generated by oxidation of chloride to hypochlorite in neutrophils, as part of the immune response against bacteria. Elemental chlorine at high concentrations is extremely dangerous and poisonous for all living organisms, and was used in World War I as the first gaseous chemical warfare agent.
- Chlorine is a stupid, ugly, mean person whom the Demon Xanth met in the events of Yon Ill Wind. Using his powers, Demon Xanth made Chlorine smart, beautiful, and kind. Her talent is to form poison from water (more like the chlorine used to clean things with). Chlorine, when she met Nimby, was mean to everyone, and was beaten by her parents. Xanth saved her from that, and she became his companion. She had only one tear left in her eyes, half a tear in each, and if she was to cry that last tear, she would become blind. In the end she shed the tear when Nimby was set on fire by her horrible parents. Chlorine is now the wife of the Demon X(A/N)th and mother of Nimbus. She is currently residing in the Nameless Castle with Xanth's mortal form, Nimby. She has a twin sister named Fluorine, who unfortunately is just as mean and nasty as Chlorine used to be

- Chlorine is an important chemical for water purification (such as water treatment plants), in disinfectants, and in bleach. Chlorine in water is more than three times more effective as a disinfectant against Escherichia coli than an equivalent concentration of bromine, and is more than six times more effective than an equivalent concentration of iodine. Chlorine is usually used (in the form of hypochlorous acid) to kill bacteria and other microbes in drinking water supplies and public swimming pools. In most private swimming pools chlorine itself is not used, but rather sodium hypochlorite, formed from chlorine and sodium hydroxide, or solid tablets of chlorinated isocyanurates. Even small water supplies are now routinely chlorinated. (See also chlorination) It is often impractical to store and use poisonous chlorine gas for water treatment, so alternative methods of adding chlorine are used. These include hypochlorite solutions, which gradually release chlorine into the water, and compounds like sodium dichloro-s-triazinetrione (dihydrate or anhydrous), sometimes referred to as "dichlor", and trichloro-s-triazinetrione, sometimes referred to as "trichlor". These compounds are stable while solid and may be used in powdered, granular, or tablet form. When added in small amounts to pool water or industrial water systems, the chlorine atoms hydrolyze from the rest of the molecule forming hypochlorous acid (HOCl) which acts as a general biocide killing germs, micro-organisms, algae, and so on.

- The use of chlorine in swimming pools has saved thousands of lives throughout history. Even though chlorine has its dangers, they are far outweighed by the good the chemical does in killing bacteria that are harmful to people using pools. Recently there has been a lot of publicity about the hazards of chlorine. Unfortunately chlorine gets the blame for the harm caused by chloramines. As an example, cars do not injure people, careless drivers injure people. Chlorine, properly regulated in a pool, does not put people at risk. Uninformed or careless pool operators put people at risk. The three main factors for safe pool water and good air quality are: 1. The chlorine level is kept between 1.5 and 2.5 with a pH between 7.3 and 7.5 2. No chloramines can be present in the pool water 3. The air circulation and dehumidification system must be functional and properly sized If the air smells like chlorine, something is wrong. That acrid smell we sometimes associate with chlorine is usually an ammonia type compound. In the swimming pool industry the cause of this odor is chloramines. Chloramines (combined chlorine) occur when free chlorine combines with ammonia and other nitrogen compounds. This combining process can be accelerated by perspiration, urine, saliva, body oils, lotions and some shampoos, soaps, fertilizers, and many industrial or household cleaners. The odor is created when water is not properly balanced. The odor intensifies when swimmers agitate the water, as in kicking or general warm-up swimming at a swim meet. The odor is worse at water level but can be extremely irritating at deck level or in the viewing area. Many times eye irritation and difficulty breathing accompany the odor. Sometimes the water may be hazy, but not always. Many times, the water will appear perfectly clear and the water test reads normal for free chlorine and pH. This has become such a widespread problem in indoor pools that people are hospitalized each year. People with asthma are particularly at risk. Most of the problems occur in indoor pools. Outdoor pools have plenty of fresh air and sunshine (ultra violet light) so they are not as susceptible to the chloramines problem. Chloramine formation can be accelerated by: 1. Swimmers not properly showering before entering pool. 2. Urination in the pool. 3. People doing a high level of aerobic activity and sweating in the water. (Note: everyone sweats when exercising in the water, the same as when they exercise on land.) 4. Residues from ammonia based cleaning products that are used on decks or in shower rooms and lavatories. 5. Residues from fertilizers used on landscaping (nitrogen based) that get tracked into building on shoes. 6. Poor air circulation and lack of fresh air introduction into the pool building. 7. Over use of “shocking” the pool for maintenance purposes. 8. Improper use of certain brands of chemicals not suitable for conditions specific to a geographic area. 9. Chloramines added to the municipal drinking water which is becoming common practice throughout the country. What to do? If chloramines are detected the most common solution is to shock the water. This means super-chlorination (break-point chlorination) which raises the level of chlorine in the pool to 10 parts per million. Normally dry chlorine powder or liquid chlorine is used to achieve super-chlorination. Recent studies show that many times this is not as effective as hyper-chlorination which is raising the level of chlorine to 20 parts per million. These methods may temporarily burn out chloramines but will also necessitate the pool being closed for a few days. More than the normal amount of fresh air will also have to be introduced during this process. Anecdotal evidence from people who have tried this solution seems to show that shocking the pool does not really help and can create a whole new set of problems. Some success has been realized with a non-chlorine shock additive. Adding an oxidizer (potassium peroxy, monosulphate with brand names Oxykleer or Oxybrite) to the water converts the available chlorine to free chlorine. If this process is done in the evening, swimmers can usually be in the pool the next morning. Fresh air introduction is still important. This is NOT a permanent solution.

Chlorine, though very reactive, is not as extremely reactive as fluorine. Pure chlorine gas does, however, support combustion of organic compounds such as hydrocarbons, although the carbon component tends to burn incompletely, with much of it remaining as soot. At 10 °C and atmospheric pressure, one liter of water dissolves 3.10 L of gaseous chlorine, and at 30 °C, 1 L of water dissolves only 1.77 liters of chlorine. Chlorine is a member of the salt-forming halogen series and is extracted from chlorides through oxidation often by electrolysis. With metals, it forms salts called chlorides. As the chloride ion, Cl−, it is also the most abundant dissolved ion in ocean water.
