A faavae vailaʻau na pau lava na o mea vailaʻau e faʻamaʻapeina faʻasaʻolotoina hydroxyl ions (OH^–). O vailaʻau vailaʻau e lauiloa foʻi ole alkali, aua e ala ile faʻateʻaina ma le faʻasaʻolotoina ole vaega ole hydroxyl, ole pH o fofo faʻateleina, o lona uiga, o le tali avea alkaline. E feteʻenaʻi ma le mea e tupu pe a acid, aua i le tulaga lena e faʻaititia ai le pH ma avea ai le vailaʻau ma mea oʻona.

O le nofoaga autu latou maua se uiga oona tofo. A maeʻa ona faʻamamaina, o iʻuga e faʻatautaia ai le eletise o loʻo i ai nei (ona o le i ai o ions) ma e masani ona caustate ma afaina ai le paʻu ma isi sela o tagata ma meaola.

O faʻavae latou te faʻapalepaleina acid, masani faia masima. Alkaline fofo foliga mai e lagona maseesee pe fasimoli; E tupu lenei mea ona latou vave maua le saponification o le gaʻo taimi nei luga o le paʻu.

O le solubility o hydroxides faalagolago i le uamea: i latou o kulupu (I) e sili ona soluble i le vai, i le isi itu, o le hydroxides o elemene ma le tikeri o oxidation (II) e itiiti soluble ma i latou o tikeri o oxidation (III) poʻo (IV) e toetoe lava a le mafai . Amines ma nucleic acid faavae o le sili ona salalau o le faatulagaina faavae.

Faʻaaogaina o faʻavae

Sodium hydroxide e lautele faʻaaogaina i pisinisi: o le mea e taʻua vai kofe. I le fausiaina o le fasimoli manu gaʻo poʻo gaʻo fualaʻau e faʻaaogaina, e vela ma hydroxide sodium, o lea ua fausia ai le sodium stearate.

Sodium hydroxide o loʻo faʻaaogaina foi i le gaosiga o umu fufulu, i le gaosiga o pepa pulp ma isi tagata fufulu fale. O leisi lautele faʻaaogaina tulaga o calcium hydroxide, o le lime o lena e faʻaaogaina i le fausiaina.
