I-Phosphoric acid ingeyesibili ngemva kwe-sulfuric acid njenge-asidi yezimboni futhi ihlezi iklelisa kumakhemikhali ayi-10 aphezulu asetshenziswa emhlabeni jikelele.Izifundazwe, kodwa isetshenziswa kwezinye izinhlelo zokusebenza eziningi. I-Phosphates yayisetshenziswa njengabakhi kanye nezithambisa amanzi. Umakhi yinto eyengezwe ezinsipho noma okokuhlanza ukuze kukhuliswe amandla azo okuhlanza.
I-Phosphoric acid isetshenziswa njengendawo emaphakathi ekukhiqizeni izithasiselo zokudla kwezilwane, amakhemikhali okwelapha amanzi, ukwelapha okungaphezulu kwensimbi, i-etching agent, kanye nemikhiqizo yokunakekela komuntu siqu efana nokuxubha amazinyo. Isetshenziswa njenge-catalyst embonini ye-petroleum ne-polymer. I-Phosphoricacid isetshenziswa ekudleni njengesilondolozi, i-acidulant, nesithuthukisi ukunambitheka; yenza iziphuzo ze-carbonated ezifana ne-Coca Cola ne-Pepsi zibe ne-asidi, zinikeze ukunambitheka okumnandi. I-Phosphoric acid isetshenziswa njenge-arust remover kanye nesicoci sensimbi. I-Naval Jelly cishe i-25% ye-phosphoric acid. Okunye ukusetshenziswa kwe-phosphoric acid kufaka phakathi ukulawula ukukhanya ekukhiqizeni ingilazi, ukudaya izindwangu, i-raber latexcoagulation, nosimende wamazinyo.
I-Phosphoric acid (H3PO4) iyi-oxoacid ebaluleke kakhulu ye-phosphorus futhi ukusetshenziswa kwayo okuyinhloko kusekwenziweni komanyolo.
Emzimbeni womuntu, i-phosphate iyinhlanganisela eyinhloko equkethe i-phosphorus. I-Phosphate iyinhlanganisela ye-inorganic futhi ingusawoti we-phosphoric acid. Ingenza ama-esters e-organic anezinhlobonhlobo zezinhlanganisela futhi lezi zibalulekile ezinqubweni eziningi ze-biochemical. I-Phosphate inefomula ye-empirical PO43-. Kuyi-molecule ye-tetrahedral, lapho i-athomu ye-phosphorus ephakathi izungezwe ama-athomu amane omoya-mpilo.
Ezinhlelweni zebhayoloji, i-phosphate ivamise ukutholakala njenge-ion yamahhala (i-phosphate ye-inorganic) noma njenge-ester ngemva kokusabela nezinhlanganisela eziphilayo (okuvame ukubizwa ngokuthi ama-organic phosphates). I-phosphate ye-Inorganic (evame ukuchazwa ngokuthi i-Pi) iyingxube ye-HPO42- ne-H2PO4- ku-pH yemvelo.
