Phosphoric acid ke motsoako oa inorganic o nang le foromo ea lik'hemik'hale H3PO4. E bonahala e le likristale tse se nang 'mala, tse bonaletsang' me li qhibiliha habonolo metsing. Asiti ea phosphoric e na le asiti 'me e ka sebetsana le litšepe ho hlahisa khase ea hydrogen, hammoho le ho itšoara ka lino tse tahang ho etsa phosphate esters.
Phosphoric acid e sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa joalo ka thepa e tala bakeng sa tlhahiso ea menontsha, lisebelisoa tsa ho hloekisa le li-additives tsa lijo. E boetse e sebelisoa ho etsa matsoai a phosphate, meriana le lits'ebetsong tsa lik'hemik'hale. Ho biochemistry, asiti ea phosphoric ke karolo ea bohlokoa ea lisele, e nkang karolo ho metabolism ea matla le DNA synthesis, har'a lits'ebetso tse ling tsa tlhaho.
Tlhahiso ea asiti ea phosphoric hangata e kenyelletsa lits'ebetso tse metsi le tse omileng. Ts'ebetso ea metsi e kenyelletsa ho futhumatsa lejoe la phosphate (joalo ka apatite kapa phosphorite) ka asiti ea sulfuric ho hlahisa asiti ea phosphoric, ha ts'ebetso e omileng e kenyelletsa calcination ea lejoe la phosphate e lateloang ke ho ntšoa ha metsi le ho itšoara ka sulfuric acid.
Tlhahisong le ts'ebelisong ea indasteri, asiti ea phosphoric e baka likotsi tse itseng tsa polokeho. Phosphoric acid e ngata haholo e senya 'me e ka baka ho teneha le ho senya letlalo le tsela ea ho hema. Ka hona, mehato e nepahetseng ea tšireletso e lokela ho nkoa ho qoba ho kopana ha letlalo le ho hema mouoane oa lona ha ho tšoaroa acid ea phosphoric. Ho feta moo, asiti ea phosphoric e boetse e baka likotsi tsa tikoloho, kaha ho tsoa ho feteletseng ho ka baka tšilafalo ea metsi le mobu. Kahoo, taolo e tiileng le mekhoa e nepahetseng ea ho lahla litšila li bohlokoa nakong ea tlhahiso le tšebeliso.
