As I said in the bình luận section that aluminium hydroxide is amphoteric i.e. It dissolves in acid, forming $ce Bạn đang xem: Reversible reaction of al(oh)3 in alkali solutions
Pritt mentioned, aluminium has vacant orbital for which free electron can reside there forming a complex salt.
Bạn đang xem: Reversible reaction of al(oh)3 in alkali solutions
$$ceAl(OH)3 + NaOH(conc.) → Na
$$ceAl(OH)3 + 3NaOH → Na3
No worries. There is also an acid-base reaction where the two combines to form a salt và water but this occurs at very high temperature and you won"t find this type of reaction occurring in laboratory. This reaction can only be find in industries.
$$ceAl(OH)3 + NaOH -><1000 C> NaAlO2 + 2H2O$$
If only aluminium was used, there would be evolution of hydrogen gas from a very similar exothermic reaction. Note for simplicity, the species is written $ceNaAlO2$ but it actually contains $ce
