phosphoric acid

Technical and food grades both are available.

Phosphoric acid is used primarily in the manufacture of fertilizers, detergents, and pharmaceuticals. In the steel industry, it is used to clean and rust-proof the product. It is also used as a flavoring agent incarbonated beverages (read the ingredients list on a can of Coca-Cola), beer, jams, jellies and cheeses. In foods, phosphoric acid provides a tart, acidic flavor. A recent study reported in the journal Epidemiology(Vol 18, PP 501-506, July 2007), found that drinking two or more cola beverages per day doubled the risk of chronic kidney disease. Cola beverages have been associated with kidney changes that promote kidney stones, which may be a result of the phosphoric acid in colas. In the manufacture of detergents, phosphoric acid is used to produce water softeners. Water softeners remove Ca2+ and Mg2+ ions from hard water. If not removed, these hard-water ions react with soap and form insoluble deposits that cling to laundry and the washing machine. Phosphates produced from phosphoric acid are used extensively as water softeners (builders) in detergents. The most widely used phosphorus compound in solid detergent mixtures is sodium tripolyphosphate, Na5P3O10. As a water softener, sodium tripolyphosphate binds to Ca2+ and Mg2+, forming soluble chemical species, called complexes or chelates. These complexes prevent the Ca2+ and Mg2+ from reacting with soap and forming deposits. Most phosphoric acid is used in the production of fertilizers. Phosphorus is one of the elements essential for plant growth. Organic phosphates are the compounds which provide the energy for most of the chemical reactions that occur in living cells. Therefore, enriching soils with phosphate fertilizers enhances plants.
