If the diarrhea slacks up the patient is worse and on come symptoms of tuberculosis, weakness, prostration, brain fag. [26] This was thought to be due to the presence of phosphoric acid, and the risk for women was found to be greater for sugared and caffeinated colas than diet and decaffeinated variants, with a higher intake of cola correlating with lower bone density. In fact, it is mainly used in the chemical industry as a reagent. Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. Phosphoric acid was again used for the liquid in these now all-but obsolete silicate cements, although the concentration and additives were different from those used with zinc phosphate cement. 1.

It may be concentrated to produce commercial- or merchant-grade phosphoric acid, which contains about 54–62% P2O5 (75–85% H3PO4). Contact with concentrated solutions can cause severe skin burns and permanent eye damage. These products may also contain chelating agents, detergents and small amounts of water-miscible solvents. This particular use of phosphoric acid, however, has stirred up a controversy, as many have raised questions regarding the health effects it may have on the human body. As a sanitizing agent in the dairy, food, and brewing industries. It is commonly used in sodas to provide a sharp or sour flavor. Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H3PO4. Thus, the chemical formula of phosphoric acid is H3PO4. Phosphoric acid is used as an electrolyte in fuel cells or in oxyhydrogen generators. This website uses cookies to improve your experience while you navigate through the website. Soft drinks containing phosphoric acid, which would include Coca-Cola, are sometimes called phosphate sodas or phosphates. Phosphoric Acid. Its salts, such as ammonium phosphates and calcium phosphates, are widely used as fertilizers. In some applications, where exterior appearance is secondary, the black phosphate coating formed on applying this acid may be left in place so that it provides further corrosion resistance. Use fructose, dextrose, and phosphoric acid as ordered by your doctor. It is also used as a cleaner in construction-related trades, so as to remove mineral deposits, cement smears, and hard water stains. Why would anyone use Phosphoric Acid? [27], This article is about orthophosphoric acid. 2.1.2 InChI. Phosphoric Acid (H 3 PO 4): Very widely used in the production of agricultural fertilizers and detergent products. Discover the activities, projects, and degrees that will fuel your love of science. Computed by LexiChem 2.6.6 (PubChem release 2019.06.18) PubChem. There are many chemicals available on the market today that are suitable for use as neutralization chemicals. To produce food-grade phosphoric acid, phosphate ore is first reduced with coke in an electric arc furnace, to make elemental phosphorus. Calcium sulfate (gypsum) is produced as a by-product and is removed as phosphogypsum. This acid is also used in many teeth whitening solutions to eliminate plaque that may be present on the surface of the teeth. There are plenty of muriatic acid uses in the industrial sector. Phosphoric acid is used as an ingredient in over-the-counter anti-nausea medications, which also happen to contain high levels of sugar, that is, glucose and fructose. Phosphoric acid (H 3 PO 4) is the leading inorganic acid produced and consumed in terms of production value and it is the second largest in terms of volume—after sulfuric acid. It is non-toxic and non-volatile in nature. You also have the option to opt-out of these cookies. Here are just a few of the things that it can do: Phosphoric acid is wonderful for preserving foods over extended periods of time. Measure liquid doses carefully. When phosphorus pentoxide is combined with water, it turns into phosphoric acid. Phosphoric acid is used as an additive and flavoring agent in both human and animal feed. Further removal of water yields superphosphoric acid with a P2O5 concentration above 70% (corresponding to nearly 100% H3PO4). We hope you are enjoying ScienceStruck! Phosphoric acid is also used as an electrolyte in copper electro-polishing for burr removal. Specific applications of phosphoric acid include: A link has been shown between long-term regular cola intake and osteoporosis in later middle age in women (but not men). Thus, phosphoric acid is an important acid which has several different applications in various industries, ranging from metallurgy to the food industry. Uses: Phosphoric acid has many applications.
