The simplest and most commonly encountered of the phosphoric acids is orthophosphoric acid, H3PO4. Indeed, the term phosphoric acid often means this compound specifically (and this is also the current IUPAC nomenclature). Two or more orthophosphoric acid molecules can be joined by condensation into larger molecules by elimination of water. Condensation of a few units yields th… Webphosphoric acid (7664-38-2) (7664-38-2) LD50 oral rat 1530 mg/kg (Rat) LD50 dermal rat ≥ 1260 mg/kg body weight Skin corrosion/irritation : Causes severe skin burns. pH: < 1 Serious eye damage/irritation : Assumed to cause serious eye damage pH: < 1 Respiratory or skin sensitization : Not classified
