Trihydrogenfosfat

Trihydrogenfosfat is the chemical name for phosphoric acid, with the chemical formula H₃PO₄. It is an inorganic acid composed of three hydrogen atoms, one phosphorus atom, and four oxygen atoms. Phosphoric acid is a mineral acid and a moderately strong acid.

In its pure form, trihydrogenfosfat is a colorless, odorless, viscous liquid at room temperature. It is highly soluble in water and forms a strong acidic solution. It is also soluble in some organic solvents. Trihydrogenfosfat is a triprotic acid, meaning it can donate three protons (H⁺ ions) in successive dissociation steps. This property makes it a versatile reagent in various chemical reactions.

Trihydrogenfosfat is one of the most important industrial chemicals. Its primary use is in the production of phosphate fertilizers, which are essential for agriculture. It is also used in the food industry as an acidulant, flavoring agent, and preservative in beverages like colas. Other applications include metal treatment, detergents, and the synthesis of various chemicals. It is found naturally in many biological systems, playing a crucial role in DNA, RNA, and ATP. Exposure to concentrated trihydrogenfosfat can cause skin and eye irritation and burns.
