Nkọwa ngwaahịa
Sodium tripolyphosphate (STP, mgbe ụfọdụ STPP ma ọ bụ sodium triphosphate ma ọ bụ TPP) bụ ihe inorganic nwere usoro Na5P3O10. Sodium triphosphate bụ nnu sodium nke polyphosphate penta-anion, nke bụ conjugate isi nke triPhosphoric Acid. Sodium tripolyphosphate na-emepụta site na kpo oku stoichiometric ngwakọta nke Disodium phosphate, Na2HPO4, na Monosodium Phosphate, NaH2PO4, n'okpuru nlezianya na-achịkwa ọnọdụ.
