Acide ya fosifori ni iya kabiri nyuma ya aside sulfurike nka acide yinganda kandi ihora ikurikirana imiti 10 yambere ikoreshwa kwisi yose.Ibihugu, ariko ikoreshwa mubindi bikorwa byinshi. Fosifate yakoreshejwe nk'ubwubatsi no koroshya amazi. Umwubatsi nikintu cyongewe kumasabune cyangwa detergentsto kongera imbaraga zo kweza.
Acide ya fosifori ikoreshwa nkigihe gito mugukora inyongeramusaruro yinyamanswa, imiti itunganya amazi, kuvura ibyuma, kuvura ibyuma, hamwe nibicuruzwa byawe bwite nkinyo yinyo. Ikoreshwa nk'umusemburo mu nganda za peteroli na polymer. Fosifori ikoreshwa mu biryo nk'uburinda, aside, hamwe no kongera uburyohe; itera aside karubone nka Coca Cola na Pepsi, ikabaha uburyohe bwa tangy. Acide ya fosifori ikoreshwa nko gukuraho arust no gusukura ibyuma. Jelly Naval ni hafi ya 25% acide fosifori. Ibindi bikoreshwa muri acide ya fosifori harimo kugenzura ububobere mu gukora ibirahure, gusiga irangi imyenda, reberi latexcoagulation, hamwe na sima y amenyo.
Acide ya fosifori (H3PO4) ni oxoacide yingenzi ya fosifore kandi ikoreshwa cyane ni mugukora ifumbire.
Mu mubiri w'umuntu, fosifate ningenzi nyamukuru irimo fosifore. Fosifate ni organic organique kandi ni umunyu wa acide fosifori. Irashobora gukora ester organique hamwe nibintu bitandukanye kandi nibyingenzi mubikorwa byinshi bya biohimiki. Fosifate ifite formulaire ya PO43-. Ni molekile ya tetrahedral, aho atome ya fosifore yo hagati ikikijwe na atome enye za ogisijeni.
Muri sisitemu y'ibinyabuzima, fosifate ikunze kuboneka haba nka ion yubusa (fosifike idafite ingufu) cyangwa nka ester nyuma yo kubyitwaramo kama kama (bakunze kwita fosifike kama). Fosifike idasanzwe (cyane cyane yitwa Pi) ni uruvange rwa HPO42- na H2PO4- kuri pH physiologique pH.
