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.

(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.
