Phosphoric acid was prepared first by Robert Boyle in 1694 by dissolving phosphorus pentoxide in water. Phosphoric acid is probably the most important compound of phosphorus. It is the second largest inorganic chemical by volume, after sulfuric acid, marketed in the United States. The single most important application of Phosphoric acid is manufacturing phosphate salts for fertilizers. Such fertilizer phosphates include sodium, calcium, ammonium, and potassium phosphates. Other applications are in metal pickling and surface treatment for removal of metal oxides from metal surfaces; electropolishing of aluminum; as a bonding agent in various refractory products such as alumina and magnesia; as a catalyst in making nylon and gasoline; as a dehydrating agent; in fireproofing wood and fabrics; in lithographic engraving; in textile dyeing; in dental cement; in coagulating rubber latex; in purifying hydrogen peroxide; and as a laboratory reagent. Here we want to discuss the properties of oral phosphoric acid.
Phosphoric acid is a colorless, odorless, crystalline solid or a thick syrupy liquid. Physical state is strength and temperature dependent. Concentrated phosphoric acid occurs as a colorless, odorless, syrupy liquid. It has a pleasing acid taste when suitably diluted. Pure phosphoric acid, also called orthophosphoric acid, is a clear, colorless, mineral acid with moderate strength. It is normally marketed as an aqueous solution of 75–85% in which it exists as a clear, viscous liquid. Food-grade phosphoric acid is used to acidify foods and beverages. It provides a tangy or sour taste and, being a mass-produced chemical, is available cheaply and in large quantities. Phosphoric acid, used in many soft drinks, has been linked to lower bone density in epidemiological studies. In brief, oral phosphoric acid is a strong acid and common chemical used in the manufacture of a wide number of products, notably porcelain and metal cleaners, detergents, and fertilisers. It is also used as a food additive and is a major constituent of many soft drinks. Low phosphate concentrations are found in drinking water to which it is added in some areas in order to reduce lead solubility.
Chemists refer to orthophosphoric acid as phosphoric acid, which is the IUPAC name for this compound. The prefix “ortho” is used to distinguish the acid from other phosphoric acids, which are generally called polyphosphoric acids. Orthophosphoric acid is a nontoxic, rather weak triprotic acid. Occurrence Phosphoric acid is a natural constituent of many fruits and their juices.
Phosphoric acid is second only to sulfuric acid as an industrial acid and consistently ranksin the top 10 chemicals used globally. States, but it is used in a number of other applications. Phosphateswere used as builders and water softeners. A builder is a substance added to soaps or detergentsto increase their cleansing power. Phosphoric acid is used as an intermediate in the production of animal feed supplements,water treatment chemicals, metal surface treatments, etching agent, and personal care productssuch as toothpaste. It is used as a catalyst in the petroleum and polymer industry. Phosphoricacid is used in food as a preservative, an acidulant, and flavor enhancer. Phosphoric acid (H3PO4) is the most important oxoacid of phosphorus and its main use is in the manufacture of fertilisers. Within the human body, phosphate is the main phosphorus-containing compound. Phosphate is an inorganic compound and is the salt of phosphoric acid. It can form organic esters with a variety of compounds and these are important in many biochemical processes. Oral Phosphoric Acid is an acidulant that is an inorganic acid produced by burning phosphorus in an excess of air, producing phosphorus pentoxide which is dissolved in water to form orthophosphoric acid of varying concentrations. Other properties of oral phosphoric acid, phosphoric acid used as a flavoring acid in cola and root beer beverages to provide desirable acidity and sourness. it is used as a synergistic antioxidant in vegetable shorten- ings. in yeast manufacture, it is used to maintain the acidic ph and provide a source for phosphorus. it also functions as an acidulant in cheese.
Fructose, dextrose, and phosphoric acid combination is used to treat nausea and vomiting. However, this combination has not been proven to be effective.

Other Applications of oral phosphoric acid: Food‐grade phosphates are used as additives in food production to function as buffers, sequestrants, acidulants, bases, flavors, cryoprotectants, gel accelerants, dispersants, nutrients, or precipitants, as well as to function as free‐flow or ion‐exchange agents. Food‐grade phosphates are used to chemically leaven cakes, cookies, pancakes, waffles, and donuts; to maintain the structure and hydration of meat, poultry, and seafood products; to improve fluidity of evaporated milk; flavor or add minerals to beverages; and to maintain the structure of canned fruit and vegetable products. Some food‐additive phosphates contain minerals other than phosphate (such as calcium, potassium, and magnesium) that are consumed by some populations in quantities below those recommended in guidelines.
Phosphoric acid is an important and weak chemical. Oral phosphoric acid is the same as phosphoric acid this is a Benefits and harms of phosphoric acid. This acid has many applications in the food industry and in cleaning materials. It is found in many beverages and fruits.
