An aqueous solution is a solution in which the solvent is water.It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula.For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). Cl(-) DTXSID6043969. UNII-Q32ZN48698. Lets take the ionic formula for Calcium Chloride is #CaCl_2#. [10] It can flow through chloride channels (including the GABAA receptor) and is transported by KCC2 and NKCC2 transporters. CTK0H5734. The chloride ion has the formula Cl-, and is a monatomic ion. c0884 It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride can be oxidized but not reduced. [12], The concentration of chloride in the blood is called serum chloride, and this concentration is regulated by the kidneys. Chloride is the most abundant extracellular anion and accounts for around one third of extracellular fluid tonicity.[8][9]. May explode under exposure to heat or fire. chloride ion. Chlorided silver electrodes are commonly used in ex vivo electrophysiology.[6]. Chloride (ion) Chlorine anion. Chlorides. It has a nitrogen ion, four hydrogen atoms, and a chloride ion. 12 Chloride Ion Conductors. Chloride ions. In terms of its acid–base properties, chloride is a very weak base as indicated by the negative value of the pKa of hydrochloric acid. The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl . It may contribute to the acidification of streams, mobilize radioactive soil metals by ion exchange, affect the mortality and reproduction of aquatic plants and animals, promote the invasion of saltwater organisms into previously freshwater environments, and interfere with the natural mixing of lakes. This makes calcium a #Ca^(+2)# cation.. Chlorine is a Halogen in the 17th column or p5 group. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. A chloride ion is much larger than a chlorine atom, 167 and 99 pm, respectively. Hydrochloric acid, ion(1-) Cl-Q32ZN48698. Chlorine ion. [citation needed], Chloride is also a useful and reliable chemical indicator of river / groundwater fecal contamination, as chloride is a non-reactive solute and ubiquitous to sewage & potable water. Chloride anion. Examples of covalently bonded chlorides are phosphorus trichloride, phosphorus pentachloride, and thionyl chloride, all three of which are reactive chlorinating reagents that have been used in a laboratory. Less frequently, the word chloride may also form part o… 212.7 g/mol. Chloride can be protonated by strong acids, such as sulfuric acid: Ionic chloride salts reaction with other salts to exchange anions. Chlorid. Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2.It is a paramagnetic solid with a high melting point. Some chloride-containing minerals include halite (sodium chloride NaCl), sylvite (potassium chloride KCl), bischofite (MgCl2∙6H2O), carnallite (KCl∙MgCl2∙6H2O), and kainite (KCl∙MgSO4 ∙3H2O). Chloride (Cl-) Chlorine(1-) Chlorine ion(1-) Chloride ion (1-) Chlorine, ion (Cl1-) CHEMBL19429. It can also hinder the denitrification process, a microbial process essential to nitrate removal and the conservation of water quality, and inhibit the nitrification and respiration of organic matter.[16]. Chloride salts such as sodium chloride are used to preserve food and as nutrients or condiments. [4] It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells. Chloride(1-) Chloride anion. [15], Increased concentrations of chloride can cause a number of ecological effects in both aquatic and terrestrial environments. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion. The ammonium chloride molecule consists of nitrogen, chloride and hydrogen atoms. Chlorine can assume oxidation states of −1, +1, +3, +5, or +7. chloride. Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. It is also found in evaporite minerals such as chlorapatite and sodalite. Its increase can also indicate the poor quality of a target sand. The chloride ion /ˈklɔːraɪd/[3] is the anion (negatively charged ion) Cl−. Salts such as calcium chloride, magnesium chloride, potassium chloride have varied uses ranging from medical treatments to cement formation. [11] Characteristic concentrations of chloride in model organisms are: in both E. coli and budding yeast are 10-200mM (media dependent), in mammalian cell 5-100mM and in blood plasma 100mM. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulsesand regulating fluid in and out of cells. appears as crystalline or powdered solids. However, some chloride ion conductors are known although their conductivity is low compared to that of fluoride ion conductors. Several neutral chlorine oxides are also known. Perchloride. Smaller quantities, though at higher concentrations, occur in certain inland seas and in subterranean brine wells, such as the Great Salt Lake, Utah and the Dead Sea, Israel. The compound is white, but typical samples are often off-white. Find Similar Structures. Chloride salts such as sodium chloride are often very soluble in water. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). In nature, chloride is found primarily in seawater, which contains 1.94% chloride. Chemical Formula of Ammonium Chloride. In addition, calcium chloride is widely used as a de-icer, since it is effective in lowering the melting point when applied to ice.[17]. Molecular Formula Cl; Average mass 35.453 Da; Monoisotopic mass 34.969402 Da; ChemSpider ID 306 Structure. Molecular Weight. Chromium(III) chloride (also called chromic chloride) describes any of several compounds of with the formula CrCl 3 • x H 2 O, where x can be 0, 5, and 6. CHEBI:17996. Calcium chloride is also used for maintaining unpaved roads and for fortifying roadbases for new construction. Many water regulating companies around the world utilize chloride to check the contamination levels of the rivers and potable water sources.[18].

The most common form of the trichloride is the dark green hexahydrate, CrCl 3 • 6H 2 O.Chromium chlorides find use as catalysts and as precursors to dyes for wool. This process converts sodium chloride into chlorine and sodium hydroxide, which are used to make many other materials and chemicals. In water, it dissociates into Na+ and Cl− ions. Salt (sodium chloride) has also been shown to change the composition of microbial species at relatively low concentrations. See more. H. Iwahara, in Encyclopedia of Materials: Science and Technology, 2001. Lithium chloride is a chemical compound with the formula Li Cl.The salt is a typical ionic compound (with certain covalent characters) , although the small size of the Li + ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83.05 g/100 mL of water at 20 °C) and its hygroscopic properties. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. in seawater, significantly worsens the conditions for pitting corrosion of most metals (including stainless steels, aluminum and high-alloyed materials). BDBM26979. The chlorate ion has the formula ClO3-, and is a polyatomic ion. Chloride definition, a salt of hydrochloric acid consisting of two elements, one of which is chlorine, as sodium chloride, NaCl. Less frequently, the word chloride may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. Wiley & Sons. Chloride has a major physiological significance, which includes regulation of osmotic pressure, electrolyte balance and acid-base homeostasis. The first oxidation, as employed in the chlor-alkali process, is conversion to chlorine gas. The structure of ammonium chloride can be represented as follows. An increase of the chlorides in the mud system may be an indication of drilling into a high-pressure saltwater formation.
