Sulfuric acid is one of the most important compounds made by the chemical industry. It is used to make, literally, hundreds of compounds needed by almost every industry. Uses of sulfuric acid By far the largest amount of sulfuric acid is used to make phosphoric acid, used, in turn, to make the phosphate fertilizers, calcium dihydrogenphosphate and the ammonium phosphates. It is also used to make ammonium sulfate, which is a particularly important fertilizer in sulfur-deficient. It is widely used in metal processing for example in the manufacture of copper and the manufacture of zinc and in cleaning the surface of steel sheet, known as "pickling", prior to it being covered in a thin layer of tin, used to make cans for food. It is also used to make caprolactam, which is converted into polyamide 6 and in the manufacture of titanium dioxide, used, for example, as a pigment. Amongst its many other uses is in the manufacture of hydrofluoric acid and phenol with propanone all of which are used in many industries. Sulfuric acid is one of the most important industrial chemicals. More of it is made each year than is made of any other manufactured chemical; more than 40 million tons of it were produced in the United States in 1990. It has widely varied uses and plays some part in the production of nearly all manufactured goods. The major use of sulfuric acid is in the production of fertilizers, e.g., superphosphate of lime and ammonium sulfate. It is widely used in the manufacture of chemicals, e.g., in making hydrochloric acid, nitric acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs. It is used in petroleum refining to wash impurities out of gasoline and other refinery products. Sulfuric acid is used in processing metals, e.g., in pickling (cleaning) iron and steel before plating them with tin or zinc. Rayon is made with sulfuric acid. It serves as the electrolyte in the lead-acid storage battery commonly used in motor vehicles (acid for this use, containing about 33% H2SO4 and with specific gravity about 1.25, is often called battery acid). ادامه مطلب

Sodium Hypochlorite is a greenish-yellow liquid commonly referred to as "Bleach." The chemical formula for Sodium Hypoclorite NaOCl.Sodium hypochlorite is used on a large scale. For example in agriculture, chemical industries, paint- and lime industries, food industries,glass industries, paper industries, pharmaceutical industries, synthetics industries and waste disposal industriesIn the textile industry hydrochloride is used to bleach textile. It is sometimes added to industrial waste water. This is done to reduce odors. Hypoclorite neutralizes sulfur hydrogen gas (SH) and ammonia (NH3). It is also used to detoxify cyanide baths in metal industries. Hypochlorite can be used to prevent a lgaeand shellfish growth in cooling towers. In water treatment, hypochlorite issued to disinfect water. In households, hypochlorite is used frequently for the purification and disinfection of the houseIn the textile industry hydrochloride is used to bleach textile.

In water treatment, hypochlorite issued to disinfect water. In households, hypochlorite is used frequently for the purification and disinfection of the house. By adding hypochlorite to water, hypochlorous acid (HOCl) is formed: Hypochlorous acid is divided into hydrochloric acid (HCl) and oxygen (O). The oxygen atom is a very strong oxidator. Sodium Hypochlorite is prepared by reacting dilute caustic soda solution with liquid or gaseous chlorine, accompanied by cooling. .
