Orthophosphoric acid ke phosphoric acid e entsoeng ka tetrahedron e le 'ngoe ea phospho-oksijene. Ka asiti ea phosphoric, athomo ea P ke sp3 hybrid, li-orbitals tse tharo tse nyalisitsoeng li etsa li-bond tse tharo tse nang le athomo ea oksijene, 'me e 'ngoe ea PO bond e entsoe ka bond e le' ngoe ho tloha phosphorus ho ea ho oksijene le li-bond tse peli tsa dp ho tloha ho oksijene ho ea ho phosphorus. A σ bond e thehoa ha para e le 'ngoe ea li-elektronike tse tsoang ho athomo ea phosphorus li hokahana le orbital e se nang letho ea athomo ea oksijene.

Temo: Phosphoric acid ke thepa e tala bakeng sa tlhahiso ea menontsha ea phosphate ea bohlokoa (superphosphate, potassium dihydrogen phosphate, joalo-joalo), hape ke thepa e tala bakeng sa tlhahiso ea phepo ea lijo (calcium dihydrogen phosphate).

Indasteri: Phosphoric acid ke ntho ea bohlokoa ea lik'hemik'hale tse tala. Mesebetsi ea eona ea mantlha ke e latelang:

1, tšoara bokaholimo ba tšepe, hlahisa filimi ea phosphate e sa keneng holim'a tšepe ho sireletsa tšepe hore e se ke ea bola.

2, e kopantsoeng le asiti ea nitric joalo ka pholishe ea lik'hemik'hale ho ntlafatsa pheletso ea bokaholimo ba tšepe.

3, tlhahiso ea lisebelisoa tsa ho hlatsoa, chefo e bolaeang likokoanyana e tala phosphate ester.

4, tlhahiso ea phosphorus-e nang le lelakabe retardant thepa e tala.

Lijo: Phosphoric acid ke e 'ngoe ea li-additives tsa lijo, lijong e le moemeli o bolila, phepo ea tomoso, cola e na le phosphoric acid. Phosphate hape ke sehlomathiso sa bohlokoa sa lijo 'me se ka sebelisoa joalo ka matlafatso ea limatlafatsi.

Moriana: Phosphoric acid e ka sebelisoa ho etsa lithethefatsi tse nang le phosphorus, joalo ka sodium glycerophosphate.
