dihydroxyphosphoric

Dihydroxyphosphoric acid, also known as phosphoric acid or orthophosphoric acid, is a mineral acid with the chemical formula H3PO4. It is a weak acid that is commonly found in nature and is used in a variety of industrial and commercial applications. In its pure form, dihydroxyphosphoric acid is a colorless, odorless solid that is soluble in water. It is also corrosive and can cause burns upon contact with skin or eyes.

Dihydroxyphosphoric acid is produced commercially through two main processes: the wet process and the thermal process. The wet process involves reacting phosphate rock with sulfuric acid, while the thermal process involves burning phosphorus in air to produce phosphorus pentoxide, which is then hydrated.

Dihydroxyphosphoric acid is used in a wide range of applications, including fertilizer production, food and beverage processing, metal treatment, and detergent manufacturing. In the food industry, it is used as an acidulant and flavoring agent in soft drinks, jams, and jellies. It is also used as a rust remover and as a component in some dental cements. Due to its corrosive nature, dihydroxyphosphoric acid should be handled with care and appropriate safety precautions should be taken.
