    Teuina

    E tatau ona faʻamaufaʻailogaina ma puipuia mai le malamalama ma teu i se nofoaga malulu.

    Aloese mai le latalata i le malosi malosi i le taimi e teu ai.

    Taofi ese mai punavai, ma e mafai ona teuina i totonu o pusa uʻamea, uʻamea vaivai poʻo pusa alumini.

    Maumau

    1. Aloese mai le pipii atu i le ea. Aloese mai le fa'afeso'ota'i ma chloride acid, okesene, ma acids.
    2. Suavai e le lanu ma faigofie ona tafe, o le a liu enaena poʻo mumu loloto pe a faʻaalia i le susulu o le la poʻo le ea. E i ai se tofo oona. E fefiloi ma le vai, ae le mautu i le vai, e faigofie ona solu i le ethanol, eter, benzene ma le chloroform, ma e le mafai ona solu i le suauu suauu. E le mafai ona soloia i alkanes.

    3. Mea tau vailaʻau: Furfuryl ava malosi e mafai ona faʻaitiitia le vaifofo ammonia nitrate siliva pe a vevela. E mautu i alkali, ae e faigofie ona resinize i lalo o le gaioiga o le acid po o le okesene i le ea. Aemaise lava, e matua'i ma'ale'ale ile malosi malosi ma e masani ona mu pe a malosi le tali. E foliga lanumoana pe a faʻavevela i se faʻafefiloi o le diphenylamine, acetic acid, ma le sulfuric acid concentrated (diphenylamine reaction).

    4. O lo'o iai i lau o le tapa'a fa'amama fa'a'a'amu, lau o le tapaa, lau tapa'a i sasa'e ma le asu.
