Production and use of salt is now produced in series by evaporation of water sea or salt water from other sources such as wells, salt water and salt lakes, and the extraction of rock salt, called halite. In 2002, production worldwide was estimated at 210 million metric tons, the top five producers (million tonnes) is the United States (40.3) China (32.9), Germany (17.7) India (14.5) and Canada (12.3). As the known uses of salt in cooking, salt is used in many applications, from pulp and paper manufacturing, the establishment the dyes in textiles and the production of soaps, detergents and other toiletries. It is the main source of chlorine and sodium hydroxide industrial, used almost all sectors. Sodium chloride is sometimes used as a desiccant and cheap for sure, because he seems to have hygroscopic properties, salty an effective method for conservation Food historically, because it draws water from bacteria through osmotic pressure to prevent them from reproducing and causing food spoilage. Even if more effective than drying, few are safe for humans to swallow. Israel and Jordan salt evaporation ponds of the southern Dead Sea. Salt mounds, Salar de Uyuni, Bolivia. The rock salt mine near Mount Morris modern, New York, USA. Evaporation reservoirs Aigues-Mortes, France. The solubility of NaCl in various solvents (G NaCl / 100 g solvent at 25 ° C) 36 H2O liquid ammonia methanol Sulfolane 3.02 0.005 1.4 formic acid, acetone, acetonitrile 9.4 5.2 0.000042 formamide Dimethylformamide 0.0003 0.04 Reference: Burgess, J. metal ions in solution (Ellis Horwood, New York, 1978) ISBN 0-85312-027-7 using synthetic sodium chloride is also the raw material used to produce chlorine, which is required for sterilization and the production of many modern materials including PVC, pesticides and resins epoxy. Industrially, elemental chlorine is usually produced by electrolysis of sodium chloride dissolved in water. Chlorine, hydrogen, this process yields hydroxides alkali sodium gas, according to the chemical equation 2NaCl 2H2O + Cl2 + H2 + 2 NaOH sodium metal is produced commercially by electrolysis of liquid sodium chloride. It is currently in a cell in which sodium chloride is mixed Down with calcium chloride to reduce the melting point below 700 ° C. As calcium is more electropositive that sodium, calcium will be formed at the cathode. This method is less expensive than the previous electrolysis method of sodium hydroxide. Sodium chloride is used in other chemical processes for the production scale of compounds containing sodium or chlorine. In the Solvay process, sodium chloride is used to carbonate production sodium and calcium chloride. In the process of Mannheim and Hargreaves in the process, is used for the production of sodium sulfate and hydrochloric acid. Organic many uses microorganisms can not live in a very salty water is extracted from their cells by osmosis. For this reason, the salt used to keep foods like bacon, smoked fish. Can also be used to separate the leeches that have acceded to food. It is also used to disinfect wounds. Pure optical glass used is a compound NaCl with a wide range of optical transmission of 200 nm 20 um. It is often used in the infrared range and is still sometimes used. NaCl crystal is soft, hygroscopic and cheap. This limits the application of environmental protection or for use in the short term (prototypes). Exposed outdoor optical NaCl "Today more severe. Rot in ZnSe crystals used in place of NaCl (for the IR spectral range). Transmitivity optical data: 92% (from 400 nm to 13 meters) Refractive Index: 1494 @ 10 million reflection loss: 7.5% @ 10 m (two surfaces) dN / dt: -36.2 x 10-6 / C@0.7m domestic use since medieval times, at least People have used salt as a cleaner rubbed into household surfaces. It is also used in many brands of shampoo, and popularly walkways of ice and ice sheets. In a time when salt water was used to clean teeth. Fight fire with a fire extinguisher D for different metals sodium chloride is the principal agent of extinction in fire extinguishers (Met-LX, Super D) used in fires in combustible metals like magnesium, potassium, sodium and NaK alloy (D). thermoplastic powder is added to the mixture, and sealing (metal stearates) materials and anti-caking agents (tricalcium phosphate) to form the extinguishing agent. When applied to Firearms, The salt acts as a heat sink, dissipating heat from the fire, and is also a bit of oxygen to smother fire exclusion. The lower crust plastic additive and helps maintain its integrity until the hot metal is cooled below its ignition temperature. This type of fire extinguisher was invented in the 1940s in payload type shown here, although the versions are stored popular pressure. common sizes are £ 30 and £ 350 laptops wheels. The weather clouds over the Pacific sea salt particles are small cloud condensation nuclei and dominant in the sea, allowing the formation clouds in the air is not contaminated by other parties. Snow removal by the addition of salt (salt) is done to make the journey easier and safer, and reduce the impact long period of heavy snow in human populations. This process is carried both by households and by governments and institutions and used to remove road salt the snow surface and sidewalks. biological functions in man a high salt intake has long been a general increase in blood pressure, especially in some individuals. More recently, been shown to reduce nitric oxide production. Nitric oxide (NO) contributes to vessel homeostasis by inhibiting of vascular smooth muscle contraction and growth, platelet aggregation and adhesion of leukocytes to endothelium. Structure chloride crystal structure crystalline sodium. Each ion has six nearest neighbors, with octahedral geometry. Main article: chloride, sodium cubic crystal system forms crystals face-centered cubic symmetry. In the latter, more chloride ions showed that the law as green spheres are arranged in a cubic close packing, while the smaller sodium ions, shown to the right as areas of money, fill all the differences between hubs. Each ion is surrounded by six ions the other species and the surrounding ions are at the vertices of a regular octahedron. This basic structure is found in many other minerals and is commonly known as or structure of the halite crystal rock salt. May be represented as a cubic face centered (fcc) network based on two atoms. The first atom is at each point of the network, and second atom is midway between the mesh network points along the edge of the FCC. It is maintained by an ionic bond which is produced by electrostatic forces is the charge difference between the ions. road salt, while salt was once a rare commodity in history, industrial production salt has plenty. Approximately 51% of world production is now used by the country roads of ice cold in winter, both in the sand pits and spread by winter service vehicles. Calcium chloride is preferred to sodium chloride, the energy release CaCl2 solution on the formation of water, heating ice or snow, which is in contact with. It also lowers the freezing point, depending on the concentration. NaCl ease there is no heat in the solution, but lower the freezing point. Calcium chloride is considered more environmentally friendly than when sodium chloride is used for ice roads, but disadvantage is that it tends to promote corrosion (of vehicles), even more than sodium chloride. NaCl is also more readily available and has no management or special storage requirements, unlike calcium chloride. Salinity (S) of water is measured in grams per kilogram of salt (1000 g) of water, and freezing are following. S (g / kg) 0 10 20 24.7 30 35 T (gel) (C) 0 -0.5 Most -1.33 -1.63 -1.08 -1.91 table salt additives sold in the market today is not pure sodium chloride . In 1911, magnesium carbonate is added to salt to make it flow more freely. In 1924, the remains of iodine in the form of sodium iodide, potassium iodide or potassium iodide were added first to reduce the incidence of simple goiter. Melting salt in the UK is primarily a single mine in Winsford in Cheshire []. Before the distribution has an anti-caking added sodium hexacyanoferrate (II) at least 100 ppm, this treatment rock salt to the free movement of vehicles cleaning Despite being stored before use. In recent years this additive has been used in table salt. Environmental impact of road salt is found in freshwater organisms and may be detrimental for aquatic plants and animals by disrupting their ability to osmoregulation. An alternative is to spread sand on the ice so the surface Gross is not slippery.
