Phosphoric Acid | 7664-38-2
Oloa Fa'amatalaga
O le phosphorous acid o loʻo i le lanu e leai se lanu, manino ma le sua suamalie poʻo le tioata rhombic; Phosphorus acid e leai se manogi ma tofo oona tele; o lona tulaga liusuavai o le 42.35 ℃ ma pe a vevela i le 300 ℃ phosphorous acid o le a avea ma metaPhosphoric Acid; e 1.834 g/cm3 lona mamafa fa'atatau; e faigofie ona solu ile vai ma fofo ile ethanol; O le phosphate acid e mafai ona faʻafefe ai le paʻu o le tagata e mafua ai le phlogosis ma faʻaleagaina ai le tino o le tagata; o le phosphorus acid e fa'aalia ai le fa'avevelaina i totonu o ipu sima; phosphate acid ua maua hydroscopicity.
Phosporic Acid Fa'aaogaina:
E mafai ona faʻaaogaina le vailaʻau faʻapitoa Phosphoric Acid e gaosia ai le tele o Phosphates, vailaʻau togafitiga electrolyte poʻo vai togafitiga vailaʻau, faʻamaʻi faʻamaʻi ma phosphoric acid ma inorganic coheretant.Phosporic acid o loʻo faʻaaogaina foi e avea o se catalyst, faʻamagoina ma mama. I le faʻapipiʻiina o alamanuia o loʻo faʻaaogaina le phosphoric acid e avea o se faʻamaʻi ele-faʻamaonia mo uʻamea; I le avea ai o se faʻatonuga o le acidity ma le meaʻai meaʻai mo le fefete food grade phosphoric acid e mafai ona faʻaogaina i meaʻai, apa meaai ma meainu mama faʻapea foʻi ma le faʻaaogaina i le gaosiga o le uaina e avea o se meaʻai mo le fefete e puipuia ai le toe gaosia o siama le aoga.

Fa'atatauga
Phosphoric Aciduse e aveese ai le pefu mai luga o u'amea Fa'aaogaina e fai ma mea e liu 'ele e ala i le fa'afeso'ota'i sa'o ma se u'amea elea, po'o mea faigaluega u'amea ma isi mea e 'elea. E fesoasoani i le fa'amamāina o minerale, sima fa'ailoga ma pisia vai malo. Fa'aaogā e fa'asa'o ai mea'ai ma meainu pei o cola. O le Phosphoric Acid o se mea taua i luga o le fata faʻatau vailaʻau e faʻafefe ai le faufau. O le Phosphoric Acid e fa'afefiloi ma le pauta o le zinc ma fai ai le zinc phosphate, ma e aoga i le sima nifo le tumau. I orthodontics, o le zinc e faʻaaogaina e fai ma vaifofo etching e fesoasoani e faʻamama ma faʻamaʻa le pito o nifo. Fa'aaogaina e fai ma fetilaisa fa'afoliga i totonu o le 'ele'ele o lo'o fa'atupuina le fa'amaina o le granule e fa'aleleia ai le fa'aogaina o le phosphorus e fa'aaogaina ma maua i le rhizosphere. Ona o lona anoano o le nitrogen (lea o lo'o i ai le amonia), e lelei mo fuala'au e mana'omia nei mea'ai i lona vaega muamua.
