However, some salts like aluminium carbonate exist hinein aqueous solution but are unstable as such; and only incomplete hydrolysis takes place for salts with strong acids, such as the halides, nitrate, and sulfate. For similar reasons, anhydrous aluminium salts cannot be made by heating their "hydrates": hydrated aluminium chloride is in fact not AlCl3·6H2O but [Al(H2O)6Schließende eckige klammerCl3, and the Al–O bonds are so strong that heating is not sufficient to break them and form Al–Cl bonds instead:[35]
Despite its prevalence in the environment, no living organism is known to metabolize aluminium salts, but this aluminium is well tolerated by plants and animals. Because of read more the abundance of these salts, the potential for a biological role for them is of interest, and studies are ongoing.
