Fa'aoga oloa
O le 625 e fa'aaogaina lautele i le gaosiga o vaila'au, lea e mafai ai ona fa'aaogaina e avea o se vaega manifinifi fausaga. 625 u'amea e mafai ona fa'aogaina i fa'aoga pe a fa'afeso'ota'i ma le suasami ma o'o ai i fa'alavelave fa'ainisinia maualuga.
Vaega masani fa'aoga: 1.
1. O vaega mo gaioiga fa'alekemiki fa'aola o lo'o iai chlorides, aemaise lava i mea e fa'aogaina ai fa'ama'i chloride acidic.
2. Digester ma tane pisapisao mo le alamanuia aano ma pepa.
3. Olo fa'a'a'ai, toe fa'a'a'a'a'a, pa'u kasa fa'asu, ili (susū), mea fa'avevesi, fa'afefe ma fa'a'a'a'a i faiga fa'avevela kasa.
4. Meafaigaluega ma vaega mo le gaosiga o talosaga i siosiomaga kasa acid.
5. Acetic acid ma le ethyl alcohol fa'atupu fa'aola. 6. Sulfuric acid condensers.
