Fa'amatalaga o oloa:
Pa'epa'e tioata pa'epa'e, liusuavai 240°C (decomposition). E le mafai ona solu i le vai malulu, ava malosi ma solu faʻalaʻau masani, soluble i vai vevela, soluble i vaifofo o le sodium hydroxide, sodium carbonate ma ammonia.
Talosaga:
(1) Faʻaaogaina e fai ma vaifofo faʻamaʻi ma faʻapipiʻi mo le gaosiga o mea lanu ata, vali vali, fesoasoani faʻafefete, vailaʻau faʻapipiʻi, faʻamaʻi toto, faʻamaʻi, faʻamautu, mea faʻapipiʻi polymerisation faʻapipiʻi, EDTA o se mea sui mo le chelating agents.
(2) E mafai ona fausia fa'amausali vai-soluble fa'atasi ma metala eleele alkaline, elemene eleele seasea ma metala suiga. I le faaopoopo atu i masima sodium, o loʻo i ai foʻi masima ammonium ma uʻamea, magnesium, calcium, copper, manganese, zinc, cobalt, alumini ma isi masima eseese, o nei masima e eseese faʻaoga.
(3) E mafai foi ona faʻaaogaina le EDTA e faʻamalo ai metala radioactive leaga mai le tino o le tagata i se faiga faʻavavevave. E faʻaaogaina foʻi e fai ma vailaʻau togafitiga mo vai.
(4) EDTA o se faʻailoga taua ma e mafai ona faʻaaogaina e titrate nickel, kopa, ma isi. E tatau ona faʻaoga faʻatasi ma le amonia e fai ma faʻailoga.
