Fa'amatalaga o oloa:
O le phosphoric acid ose acid inorganic masani ma o se ala i le malosi malosi. O lona acidity e sili atu le vaivai nai lo le malosi malosi e pei ole sulfuric acid, hydrochloric acid ma le nitric acid, ae sili atu le malosi nai lo mea vaivai e pei ole acetic acid, boric acid ma carbonic acid. O le phosphoric acid e tali atu i le sodium carbonate ile Chemicalbook eseese pH e maua ai masima acid eseese. E mafai ona faaosofia ai le paʻu e mafua ai le mumū ma faʻaumatia ai maso. O le acid phosphoric concentrated e i ai se aafiaga erosive pe a faʻavevela ile porcelain. E hygroscopic, fa'amaufa'ailoga.
Talosaga:
(1) Faʻaaogaina faʻapitoa i alamanuia phosphate, eletise eletise, fale gaosi oloa, alamanuia suka, fetilaisa tuʻufaʻatasia ma isi. I totonu o le fale gaosi meaʻai e pei o le acidifier, faʻafefete nutrient, ma isi.
(2) Faʻaaogaina e fai ma faʻamalosi mo le faʻamamaina o le ethylene e maua ai le ethanol, maualuga mama phosphate, gaosiga o vailaʻau, vailaʻau vailaʻau.
(3) Faʻaaogaina tele i le gaosiga o vailaʻau vailaʻau, vailaʻau, meaʻai ma meaʻai faʻapipiʻi, faʻafefe afi ma phosphates eseese.
(4) I le gaosiga o paipa vaalele silicon ma fesoʻotaʻiga tuʻufaʻatasia, e masani ona faʻaaogaina ata alumini mo taʻitaʻi eletise, o le manaʻomia mo le photolithography o le alumini ata, faʻaaogaina o le phosphoric acid e pei o le faʻamamaina o le acidic corrosive. E mafai ona faia i le acetic acid.
(5) E mafai ona faʻaaogaina e fai ma sui souring ma faʻafefete nutrient. E mafai ona fa'aaogaina e fai ma sui fa'asao mo fa'amamafa, tu'u apa, ma meainu fa'afou. Fa'aaogaina e fai ma fa'afefete mea'ai mea'ai i le fa'againa e puipuia ai le fa'atupuina o siama ta'avale.
(6) susu phosphoric acid e masani ona faʻaaogaina e fai ai phosphates eseese, e pei o le ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, ma isi ma phosphates condensed. E fa'aaogaina le phosphoric acid e fai ai le calcium phosphate mo fafaga. Fa'aaogaina mo togafitiga fa'aeletise i luga o le u'amea, fa'apipi'iina le vaifofo fa'apololei eletise ma vaifofo fa'apolokalame vaila'au mo le fa'aliga o oloa alumini.
(7) Alamanuia tau vailaau mo le gaosiga o le sodium glycerophosphate, uʻamea phosphate, ma isi, ae faapea foi mo le gaosiga o le zinc phosphate e pei o nifo Chemicalbook faatumu nifo pipii. Fa'aaogaina e fai ma fa'amalosi mo le fa'a'ele'ele o le resini phenolic, vali ma le gaosiga o mea fa'alatalata ole desiccant. Alamanuia lomitusi mo le saunia o solo ese stains ipu lanu lanu i luga o le vaifofo faamamaina. E fa'aaogaina fo'i e fa'asusu ai le vai fa'ama'i mo laau afitusi. Alamanuia metallurgical mo le gaosiga o le phosphoric acid refractory palapala, faaleleia le olaga o le ogaumu uamea. O le so'o fa'amausali o pa'u pa'u ma mea mata mo le gaosia o mea fa'apipi'i. Fa'aaogaina i fale vali e fai ma vali antirust mo u'amea.
(8) Fuafuaga o le chromium, nickel, vanadium tuufaatasiga i le uamea, puipuiga ele uʻamea, coagulant paʻu, faʻamautinoaina o le nitrogen e le o se polotini i serum, cholesterol atoa ma kulukose toto atoa ma isi. Crystallized phosphoric acid e masani ona faʻaaogaina i microelectronics, maʻa maualuga-malosi, tioata laser ma isi gaioiga gaosiga, e avea o se faʻamaʻi mama maualuga, mea faʻafomaʻi.
