Phosphoric acid wani fili ne na inorganic tare da dabarar sinadarai H3PO4. Yana bayyana azaman mara launi, lu'ulu'u masu haske kuma yana da sauƙin narkewa cikin ruwa. Phosphoric acid acidic ne kuma yana iya amsawa tare da karafa don samar da iskar hydrogen, da kuma amsawa da barasa don samar da esters phosphate.
Phosphoric acid ana amfani dashi sosai a masana'antu daban-daban, gami da azaman ɗanyen abu don samar da takin mai magani, abubuwan tsaftacewa, da ƙari na abinci. Ana kuma amfani da shi wajen kera gishirin phosphate, da magunguna, da kuma hanyoyin sinadarai. A cikin nazarin halittu, phosphoric acid wani muhimmin sashi ne na sel, yana shiga cikin makamashin makamashi da haɗin DNA, a tsakanin sauran hanyoyin nazarin halittu.
Samar da phosphoric acid yawanci ya haɗa da tsarin jika da bushewa. Tsarin rigar ya haɗa da dumama dutsen phosphate (kamar apatite ko phosphorite) tare da sulfuric acid don samar da phosphoric acid, yayin da bushewar tsari ya ƙunshi calcination na dutsen phosphate wanda ya biyo bayan hakar rigar da amsawa tare da sulfuric acid.
A cikin samarwa da amfani da masana'antu, phosphoric acid yana haifar da wasu haɗarin aminci. Babban phosphoric acid yana da ƙarfi sosai kuma yana iya haifar da haushi da lalacewa ga fata da fili na numfashi. Don haka, ya kamata a ɗauki matakan kariya masu kyau don guje wa haɗuwa da fata da kuma shakar tururinsa yayin sarrafa sinadarin phosphoric. Bugu da ƙari, phosphoric acid kuma yana haifar da haɗarin muhalli, saboda yawan zubar da ruwa zai iya haifar da gurɓataccen ruwa da ƙasa. Don haka, kulawa mai tsauri da ingantattun hanyoyin zubar da shara suna da mahimmanci yayin samarwa da amfani.
