Phosphoric acid, eo hape e tsejoang e le orthophosphoric acid, ke asiti ea inorganic e sebelisoang haholo liindastering tse fapaneng. E na le asiti e matla ka mokhoa o itekanetseng, foromo ea eona ea lik'hemik'hale ke H3PO4, 'me boima ba eona ba molek'hule ke 97.995. Ho fapana le li-acid tse ling tse sa tsitsang, phosphoric acid e tsitsitse ebile ha e robehe habonolo, e etsa hore e be khetho e tšepahalang bakeng sa mefuta e fapaneng ea likopo. Le hoja asiti ea phosphoric e se matla joaloka hydrochloric, sulfuric, kapa nitric acids, e matla ho feta acetic le boric acid. Ho feta moo, asiti ena e na le litšobotsi tse akaretsang tsa asiti mme e sebetsa joalo ka asiti e fokolang ea tribasic. Ho bohlokoa ho hlokomela hore asiti ea phosphoric ke hygroscopic mme e monya mongobo habonolo moeeng. Ho phaella moo, e na le monyetla oa ho fetola pyrophosphoric acid ha e futhumala, 'me tahlehelo e latelang ea metsi e ka e fetolela ho metaphosphoric acid.
