I-asidi ye-Phosphoric yeyesibini kuphela kwi-asidi ye-sulfuric njenge-asidi ye-industrial kwaye ihlala ibeka phakathi kweekhemikhali ezili-10 eziphezulu ezisetyenziswa jikelele. I-Phosphates yayisetyenziswa njengabakhi kunye nezithambisa amanzi. Umakhi yinto eyongeziweyo kwiisepha okanye kwisicoci sokwandisa amandla abo okucoca.
I-asidi ye-Phosphoric isetyenziswa njengendawo ephakathi kwimveliso yezongezo zokutya kwezilwanyana, iikhemikhali zokunyanga amanzi, unyango lomphezulu wesinyithi, i-etching agent, kunye neemveliso zokhathalelo lomntu ezifana nentlama yamazinyo. Isetyenziswa njenge-catalyst kwishishini le-petroleum kunye ne-polymer. I-Phosphoricacid isetyenziswa ekutyeni njengento egcinayo, i-acidulant, kunye ne-flavour enhancer; yenza iziselo ze-carbonated ezifana ne-Coca Cola kunye ne-Pepsi, zinike incasa emnandi. Iasidi yePhosphoric isetyenziswa njengesisusa irust kunye nesicoci sesinyithi. I-Naval Jelly imalunga ne-25% ye-asidi ye-phosphoric. Olunye usetyenziso lwe-asidi ye-phosphoric lubandakanya ukulawula ukukhanya kwimveliso yeglasi, ukudaya amalaphu, irabha latexcoagulation, kunye neesamente zamazinyo.
I-Phosphoric acid (H3PO4) yeyona nto ibalulekileyo ye-oxoacid ye-phosphorus kwaye eyona nto isetyenziswayo kukwenziwa kwezichumisi.
Emzimbeni womntu, iphosphate yeyona nto iphambili enephosphorus. I-Phosphate yi-inorganic compound kwaye yityuwa ye-phosphoric acid. Inokwenza i-esters ye-organic kunye neentlobo ezahlukeneyo zeekhompawundi kwaye ezi zibalulekile kwiinkqubo ezininzi ze-biochemical. Iphosphate inefomula yobungqina PO43-. Yimolekyuli ye-tetrahedral, apho i-athomu ye-phosphorus esembindini ijikelezwe ziiathom ezine ze-oksijini.
Kwiinkqubo zebhayoloji, i-phosphate isoloko ifumaneka njenge-ion yasimahla (i-inorganic phosphate) okanye njenge-ester emva kokusabela kwi-organic compounds (edla ngokubizwa ngokuba yi-organic phosphates). I-Inorganic phosphate (ikakhulu ichazwa njenge-Pi) ngumxube we-HPO42- kunye ne-H2PO4- kwi-pH ye-physiological.
