Salt USES

Besides making foods delicious. It’s believed there are more than 14,000 uses of salt, to meet this need; we employ a variety of production processes that have moved on a great deal since the Romans evaporated brine in small lead pans.

From the dawn of civilization, salt has been a key factor in economic, religious, social and political development. In every part of the world, salt has been the subject of superstition, folklore, and warfare, it has even been used as currency Salt (compound), also sodium chloride, chemical compound that has the formula NaCl. The term salt is also applied to substances produced by the reaction of an acid with a base, known as a neutralization reaction. Salts are characterized by ionic bonds, relatively high melting points, electrical conductivity when melted or when in solution, and a crystalline structure when in the solid state,

Salt IN INDUSTRIES
                       Sir Humphrey Davy (1778-1829) first separated salt into its constituent parts of sodium and chlorine in 1807. At the time, no one could think of anything useful to do with them, but subsequently their properties became the bedrock for many manufacturing industries.

1807: Managed to obtain Potassium from molten potash and Sodium from Common Salt by passing a current through them. He published the results in November at his Bakerian lecture.1808: Through electrolysis he managed to discover Magnesium, Calcium, Barium and Strontium.1810: Michael Faraday (Discoverer of Benzene, Inventor of the Dynamo and main architect of Classical Field Theory.) Begins attending Davy's lectures. Davy's work on Chlorine showed that muriatic or marine acid was made of Chlorine and Hydrogen only thus discounting Lavoisier's theory that all acids must contain Oxygen.1811: Faraday sends Davy a large bound selection of his notes on his lectures which impress Davy tremendously. Davy took him on as his assistant due to a temporary blindness he had contracted after an explosion in his laboratory the previous year. (Davy was later to twice block Faraday's election to a Fellowship of the Royal Society some say from professional jealousy).1812: Davy received his Knighthood. Date and Place of Birth: 17th December 1778, Penzance, Cornwall, England. Date and Place of Death: 29th May 1829, Geneva, Switzerland. Died at the Age: 50.

Today, salt keeps our industries alive. The properties of chlorine and sodium and the principal compounds from them, make it one of the most important of the basic raw materials which industry uses. Chlorine compounds of commercial importance include hydrochloric acid, and sodium hypochlorite. Important sodium compounds include sodium carbonate (soda), sodium sulphate, baking soda, sodium phosphate, and sodium hydroxide.
Today the greatest single use for salt is as a feedstock for the production of chemicals. The chloralkali industry uses salt, primarily as salt in brine from captive brine wells, to produce chlorine and caustic soda. Demand for salt in to produce chemicals fell from 25 million metric tons in 1974 to a low of 16.7 million metric tons in 1992. However, chemical use rebounded in 1994 to 18.4 million metric tons. Much of the decreased demand for chlorine was attributed to environmental concerns about dioxins. Salt is also used to make sodium chlorate and metallic sodium by electrolysis and, sodium sulphate and hydrochloric acid by reacting with sulphuric acid.
Salt is used directly by many industries such as in textile dyeing and in "industrial" uses like curing animal hides whether done commercially or at home. Salt is also considered the "aspirin of aquaculture" and used by fish farmers to keep their "product" healthy. 

CHEMICALS FROM SALT
Hydrogen is used in the manufacture of ammonia and margarine. Chlorine is used to sterilize water, and in the manufacture of hydrochloric acid, PVC and CFCs. Sodium hydroxide is used in the manufacture of soap, paper and ceramics.

• Salt as a raw material
• The chlor-alkali industry
• Uses of hydrogen, chlorine and sodium hydroxide

Salt as a raw material
Common salt is sodium chloride, NaCl. It can be made in the laboratory by the reaction of sodium with chlorine. However, it is found naturally in large amounts in underground deposits and sea water. It is mined from the underground deposits or obtained by evaporating the water from sea water.

Uses of sodium chloride

• Salt is widely used in the food industry as a preservative and flavour enhancer. While too much salt taken in with food is bad for us, a certain amount of salt is vital for human health. In fact you can die from lack of salt!
• Salt is used to treat icy roads in the winter. It lowers the melting point of the ice on the roads so that it melts, even when the temperature is below 0°C.
• Sodium chloride is the raw material for the manufacture of hydrogen, chlorine and sodium hydroxide by electrolysis. This is an important industrial process because these substances have many uses

Electrolysis (passing an electrical current through a solution of salt in water) produces:
Uses of hydrogen, chlorine and sodium hydroxide
You need to be able to describe some of the many uses of the products of the electrolysis of brine: hydrogen, chlorine and sodium hydroxide. All three products are useful individually, but can also be combined together to make two important new products. Sodium hydroxide and chlorine can be made into sodium chlorate (I) (sodium hypochlorite); which is sold as a solution. Sodium chlorate (I) is a strong oxidising agent, and is excellent for killing bacteria, but highly explosive. It is used in the production of sodium hypochlorite (common name - bleach), used in the home.  Hydrogen and chlorine react together to form hydrogen chloride. This is made into hydrochloric acid by dissolving it in water. Hydrochloric acid made in this way is very pure, and can be used safely in the food and pharmaceutical industries. 
NaCl is absolutely essential to life on earth. And sodium chloride has literally thousands of uses! One of that chlorine. It plays a key role in the manufacture of thousands of products we depend on every day, including volleyballs, computers, cars, pool chemicals, medicines and cosmetics.
Those are just a small sampling of the many items that are made using chlorine.
