Phosphoric Acid
Amioga fa'aletino:
1. Suavai manino le lanu, Leai se manogi faʻafefe
2. Melting point 42 ℃;vevela 261 ℃.
3.Miscible ma le vai i soo se fua faatatau
faleoloa:
1. Teu i totonu o se faleteuoloa malulu ma ea.
2. Tausia mai le afi ma le vevela.
3. Ua faʻamaufaʻailogaina le afifi.
4. E tatau ona teuina ese mai mea faigofie (mu) mu, alkalis, ma pauta u'amea malosi, ma aloese mai le teuina fefiloi.
5. O le nofoaga e teu ai e tatau ona faʻapipiʻiina i mea talafeagai e aofia ai le leak.

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'aisi fa'ato'a, Fa'afefete Nutri-ents, , e pei o le coca-cola.
Fa'aoga fa'afoma'i: e maua ai vaila'au o lo'o i ai le phos-phorus, e pei o le Na 2 Glycerophosphat
