Chlorine is commonly used to purify water, but because it can also be used to make poisonous chlorine gas, the sanctions regime included banning its manufacture under any conditions throughout Iraq and its import severely restricted.

Chlorine exists in all odd numbered oxidation states from − 1 to + 7, as well as the elemental state of zero and four in chlorine dioxide ( see table below, and also structures in chlorite ).

Chlorine can assume oxidation states of − 1, + 1, + 3, + 5, or + 7 within the corresponding anions Cl < sup >−</ sup >, ClO < sup >−</ sup >, ClO < sub > 2 </ sub >< sup >−</ sup >, ClO < sub > 3 </ sub >< sup >−</ sup >, or ClO < sub > 4 </ sub >< sup >−</ sup >, known commonly and respectively as chloride, hypochlorite, chlorite, chlorate, and perchlorate.

Chlorine ( ; from ) is a chemical element with symbol Cl and atomic number 17.

Chlorine is in the halogen group ( 17 ) and is the second lightest halogen after fluorine.

Chlorine is a component of various compounds, including table salt.

Chlorine forms compounds with almost all of the elements to give compounds that are usually called chlorides.

Chlorine gas reacts with most organic compounds, and will even sluggishly support the combustion of hydrocarbons.

Chlorine gas only exists in a neutral or acidic solution.

Chlorine is very rare in lunar regolith, so the design recycled it.

Chlorine accepts the electron and its oxidation state is reduced to − 1.

Chlorine is a gas, bromine is a liquid and iodine is a solid.

The limiting element was Chlorine, an essential element to process regolith for Aluminium.

Chlorine is very rare in lunar regolith, and a substantially faster rate of reproduction could be assured by importing modest amounts.

Chlorine is a skin and mucous membrane irritant that is used to make water safe for bathing or drinking.

Chlorine gas-both a bleaching agent and a maturing agent, but one that weakens gluten development.

Chlorine gas.

Chlorine in the form of a mixture of chloride of lime and chloride of iron was added to a highly colored water supply over the period of 1902 to 1921.

Chlorine gas was first used on a continuing basis to disinfect the water supply at the Belmont filter plant, Philadelphia, Pennsylvania beginning in 1913.

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.

Salt-Sodium Na < sup >+</ sup > and Chlorine Cl < sup >-</ sup > ions are pumped out of the liquid gradually lowering the concentration in the exiting liquid, but, using the countercurrent multiplier mechanism, always pumping against a constant and small osmotic difference.

Chlorine most strongly attracts extra electrons ; mercury most weakly attracts an extra electron.

Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms.

Chlorine solutions can be generated on site by electrolyzing common salt solutions.

in 2002 as a preparation for the attack 4 kg of Chlorine had been bought and packed for the attack, for an unknown reason it was not used and passed to Abbas al-Sayyid instead.

Chlorine is produced at the anode, and sodium is produced at the cathode where it forms a sodium-mercury amalgam with the mercury.

The interests of chloralkali product manufacturers are represented at regional, national and international levels by associations such as Euro Chlor and The World Chlorine Council.

Chlorine is formed at the anode, while sodium formed at the cathode dissolves into the mercury, making sodium amalgam.

* Chlorine pentafluoride ( ClF < sub > 5 </ sub >) is a colourless gas, made by reacting chlorine trifluoride with fluorine at high temperatures and high pressures.

That song uses portions of the Twilight Zone's theme song -- and it also tells you to " Beware of the Pool " and " Don't Let the Chlorine in Your Eyes Blind You to the Big Surprise that's waitin ' for you at the bottom of the bottomless blue blue blue pool ".

Davy further claimed that elements that were then believed to be gases, such as nitrogen and hydrogen could be liquified under the right conditions and would then behave as metals.

In these systems, the plants can still up-root themselves in the liquified soil under seismic load and therefore it is required that the plants be secured to the system to prevent them from falling from the wall.

Other examples of pressure vessels are diving cylinders, recompression chambers, distillation towers, pressure reactors, autoclaves, and many other vessels in mining operations, oil refineries and petrochemical plants, nuclear reactor vessels, submarine and space ship habitats, pneumatic reservoirs, hydraulic reservoirs under pressure, rail vehicle airbrake reservoirs, road vehicle airbrake reservoirs, and storage vessels for liquified gases such as ammonia, chlorine, propane, butane, and LPG.

Originally, it was liquified under high pressure and stored in several high-pressure vessels until it was found that low-temperature liquefied nitrous oxide gave better performance due to improved charge cooling.

* Class 2 Gases, including compressed, liquified and dissolved under pressure gases and vapors

If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal ; in all other cases a liquid or liquified medium ( such as ink or wax ) is used, usually in another color than the paper.

A milestone was achieved on July 10, 1908 when Heike Kamerlingh Onnes at Leiden University in the Netherlands produced, for the first time, liquified helium, which has a boiling point of 4. 2 kelvin at atmospheric pressure.

The original ACES design was fairly complex ; the air was first liquified in the heat exchanger cooled by liquid hydrogen fuel, then pumped into a low pressure tank for short term storage.

The critical temperature is the temperature above which the gas cannot be liquified irrespective of the amount of pressure applied.
