Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. Th… WebNov 13, 2024 · That's why I suspect La(OH)3 is the formed precipitate. What happens is, I am trying to create a LaCl3 in pH 7-7.4. It is not only impossible (due to the starting pH of the solution being low pH, there's no way or not make sense to use HCl), but solubility is so low, a precipitate is formed rapidly.
