Phosphoric acid

fa'amatalaga puupuu:

O se mea masani inorganic acid, phosphoric acid e le faigofie ona faʻafefe, e le faigofie ona pala, toetoe lava a leai se faʻamaʻi, ma le masani o le acid, o se vailaʻau vaivai, o lona acidity e sili atu le vaivai nai lo le hydrochloric acid, sulfuric acid, nitric acid, ae malosi atu nai lo le acetic. acid, boric acid, ma isi. Phosphoric acid e faigofie ona faʻafefe i le ea, ma o le vevela o le a leiloa vai e maua ai le pyrophosphoric acid, ona toe leiloa lea o le vai e maua ai metaphosphate.

Fa'aaogaina o Mea

Fa'aoga autu

Fa'ato'aga:Phosphoric acid o se mea mataʻutia mo le gaosiga o faʻamaʻi phosphate taua (superphosphate, potassium dihydrogen phosphate, ma isi), ma o se mea mataʻutia mo le gaosiga o meaʻai (calcium dihydrogen phosphate).

Alamanuia:O le phosphoric acid o se mea fa'ameamea taua.O ana galuega tauave autu e faapea:

1, togafitia le uʻamea uʻamea, faʻatupuina le phosphate film i luga o le uʻamea e puipuia ai le uamea mai le pala.

2, faʻafefiloi ma le nitric acid e avea o se vailaʻau kemisi e faʻaleleia ai le maeʻa o le uʻamea.

3, o le gaosiga o sapalai fufuluina, vailaau e tineia ai manu mea mata phosphate ester.

4, o le gaosiga o phosphorus-e aofia ai mea mata retardant mumu.

Mea'ai:Phosphoric acid o se tasi o meaʻai faʻaopoopo, i meaʻai e pei o se sui oona, meaʻai fefete, cola o loʻo i ai le phosphoric acid.O le Phosphate ose mea'ai fa'aopoopo taua ma e mafai ona fa'aaogaina e fai ma fa'asusuga fa'asusu.

Vaila'au:E mafai ona fa'aogaina le phosphoric acid e fai ai vaila'au o lo'o iai phosphorus, e pei ole sodium glycerophosphate.
