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.
