phosphoric acid

 [fos-for´ik]
a crystalline acid formed by oxidation of phosphorus; its salts are called phosphates.

phos·phor·ic ac·id

(fos-fōr'ik as'id),
Orthophosphoric acid; H3PO4; a strong acid of industrial importance, m.p. 42.35°C; dilute solutions have been used as urinary acidifiers and as dressings to remove necrotic debris. In dentistry, it constitutes about 60% of the liquid used in zinc phosphate and silicate cements; solutions in varying concentrations are used to etch enamel and dentin surfaces prior to application of various types of resins.

phosphoric acid

/phos·phor·ic ac·id/ (fos-for´ik)
1. orthophosphoric acid, the monomeric form H3PO4.
2. a general term encompassing the monomeric (orthophosphoric acid), dimeric (pyrophosphoric acid), and polymeric (metaphosphoric acid) forms of the acid. Diluted p.a. is used as a pharmaceutical solvent and a gastric acidifier.

phosphoric acid (H3PO4)

[fosfôr′ik]
a clear, colorless, odorless liquid that is irritating to the skin and eyes and moderately toxic if ingested. It is used in the production of fertilizers, soaps, detergents, animal feeds, and certain drugs.

A strong acid of industrial importance; dilute solutions have been used as urinary acidifiers and as dressings to remove necrotic debris. In dentistry, it comprises about 60% of the liquid used in zinc phosphate and silicate cements; solutions are used for conditioning enamel surfaces before applications of various types of resins.

phosphoric acid

an important component of NUCLEIC ACIDS, connecting the pentose sugars to form a POLYNUCLEOTIDE CHAIN.

phos·phor·ic ac·id

(fos-fōr'ik as'id)
Orthophosphoric acid. In dentistry, it constitutes about 60% of the liquid used in zinc phosphate and silicate cements; solutions in varying concentrations are used to etch enamel and dentin surfaces to improve mechanical bonds before application of various types of resins. Sometimes used as a component in zinc phosphate cement.
