CHEMISTRY GLOSSARY
aluminate
aluminatAluminate is a salt formed when aluminium hydroxide or y-alumina is dissolved in solutions of strong bases, such as sodium hydroxide. Aluminates exist in solutions containing the aluminate ion, commonly written [Al(OH)4]-. In fact the ion probably is a complex hydrated ion and can be regarded as formed from a hydrated Al3+ ion by removal of four hydrogen ions:
[Al(H2O)6]3+ + 4OH- = 4H2O + [Al(OH)4(H2O)2]-
Other aluminates and polyaluminates, such as [Al(OH)6]3- and [(HO)3AlOAl(OH)3]2-, are also present.
