aluminate

Chemistry

A salt formed when aluminium hydroxide or γ‎-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:
${{[Al (H}_{2} {O)}_{6}]}^{3 +} {+ 4 OH}^{-} \to {4 H}_{2} O + {[Al (OH)}_{4} {{(H}_{2} O)}_{2}]^{-}$
Other aluminates and polyaluminates, such as [Al(OH)₆]³⁻ and [(HO)₃AlOAl(OH)₃]²⁻, are also present. See also aluminium hydroxide.
