Phosphoric Acid

Phosphoric acid is a clear, colorless, viscous liquid at room temperature, odorless and non-volatile, with a melting point of 42.4 °C and a boiling point of 158 °C (at 100 mmHg); it is typically handled as an aqueous solution (e.g., 75–85 wt%). It is an inorganic oxyacid of phosphorus and classified as a triprotic mineral acid. Phosphoric acid serves primarily as a precursor to phosphate salts and esters, and is widely used in the production of fertilizers (e.g., ammonium phosphates), food-grade additives (e.g., acidulants and preservatives), and metal treatment agents (e.g., rust inhibitors and surface conditioners). Its principal application areas include agriculture, food and beverage manufacturing, water treatment, and industrial cleaning formulations.

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; it acidifies carbonateddrinks such as Coca Cola and Pepsi, giving them a tangy flavor. Phosphoric acid is used as arust remover and metal cleaner. Naval Jelly is approximately 25% phosphoric acid. Other usesfor phosphoric acid include opacity control in glass production, textile dyeing, rubber latexcoagulation, and dental cements.
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.
