Fa'aaogā:
Fa'ato'aga fa'aoga: mea mata o le phosphate fertilizerand fafaga meaʻai
Alamanuia fa'aoga: vaila'au mata'utia
1. Puipui le uamea mai le pala
2. Fa'afefiloi ma le nitric acid e pei o vaila'au fa'alelei e fa'aleleia ai le pito i luga ole u'amea
3.Material o le phosphatide lea e faʻaaogaina mo le gaosiga o oloa fufulu ma iniseti
4.O le gaosiga o le phosphorus o loʻo i ai mea faʻafefe.
Fa'aoga mea'ai fa'aopoopo: fa'a'a'ai fa'ato'aga, Fa'afefete Nutri-ents, , e pei o le coca-cola.
Fa'aaogāga fa'afoma'i: e maua ai vaila'au o lo'o iai le phos-phorus, pei o le Na 2 Glycerophosphat
Phosphoric acid poʻo le orthophosphoric acid, vailaʻau faʻasolosolo H3PO4, mamafa mole 97.9724, o se vailaʻau inorganic masani, o se vailaʻau malosi malosi. E maua i le fa'amavaeina o le phosphorus tetroxide i le vai vevela. O le Orthophosphoric acid e maua faʻapisinisi e ala ile togafitia ole apatite ile sulfuric acid. O le phosphoric acid e faʻamama faigofie ile ea. O le vevela e aveesea ai le vai i le pyrophosphoric acid, ma atili leiloa ai le vai ile metaphosphate. Phosphoric acid e masani ona faʻaaogaina i vailaʻau, meaʻai, faʻalaʻau ma isi alamanuia, ma e mafai foi ona faʻaaogaina e avea o se vailaʻau faʻamalosi.
Fauga meafaitino
Orthophosphate o se phosphoric acid e aofia ai le phospho-oxygen tetrahedron e tasi. I le mole mole o le phosphoric acid, o le P atom e sp3 hybridized, tolu orbital hybrid e fausia ai ni sigma se tolu ma le okesene atom, ma le isi P - O fusi e faia i le tasi sigma bond mai le phosphorus i le okesene ma lua d-pπ fusi mai. okesene i phosphorus. O le sigma bond e fausia e ala i le faamaopoopoina o se paipa eletoni e tasi mai se phosphorus atom i se orbital avanoa o se atoma okesene. d←p fa'atupuina e ala i le fa'apipi'iina o le py ma le pz o le okesene fa'atasi ma le dxz ma le dyz avanoa avanoa o le phosphorus atoms. Talu ai o le 3d malosi o phosphorus atoms e sili atu le maualuga nai lo le 2p malosi o le okesene atoms, o le molecular orbitals e le lelei tele, o lea o le PO bonds e tolu faʻamaufaʻailoga i le numera, ae vaeluagalemu i le va o le tasi ma le faʻalua faʻatasi i tulaga o le malosi malosi. ma le umi o fusi. O le iai o fa'amauga o le hydrogen i le H3PO4 mama uma ma ona vai tioata e mafai ona fa'atatau i le viscosity o le vaifofo o le phosphoric acid.
Talosaga fanua
Faatoaga: Phosphoric acid o se mea mataʻutia mo le gaosiga o phosphate fertilizers taua (calcium superphosphate, potassium dihydrogen phosphate, ma isi), faʻapea foʻi ma le gaosiga o meaʻai (calcium dihydrogen phosphate).
Alamanuia: O le phosphoric acid ose vaila'au mata'utia taua. O ana galuega tauave autu e faapea:
Fa'ata'atia le u'amea e fai ai se ata phosphate e le mafai ona solu i luga ole u'amea e puipuia ai le uamea mai le pala.
Fa'aaogaina e fai ma fa'apolokiki vaila'au fa'afefiloi ma le nitric acid e fa'aleleia atili ai le fa'ai'uga o luga o u'amea.
Le gaosiga o vailaau fa'ama'i, vailaau fa'ala'au fa'atosina mea mata phosphate ester.
Meafaitino mo le gaosiga o phosphorous mumu mumu.
Mea'ai: Phosphoric acid o se tasi lea o mea'ai fa'aopoopo, i mea'ai e pei o se so'o oona sui, fa'afefete mea'ai mea'ai, Coca-Cola o lo'o i ai le phosphoric acid. Phosphates o ni mea'ai fa'aopoopo taua ma e mafai ona fa'aaogaina e fa'aleleia ai mea'ai.
Vailaau Fa'afomai: E mafai ona fa'aogaina le phosphoric acid e fai ai vaila'au phosphorous, pei ole sodium glycerophosphate.
