Addition of a base to water will reduce the hydrogen cation concentration and therefore increase the hydroxide ion concentration (decrease pH, increase pOH) even if the base does not itself contain hydroxide. For example, 1350:
In mildly acidic solutions, the hydroxo/hydroxido complexes formed by aluminium are somewhat different from those of boron, reflecting the greater size of Al(III) vs. B(III). The concentration of the species is very dependent on the total aluminium concentration. Various other hydroxo complexes are

Basic aluminium hydroxide AlO(OH), which may be present in bauxite, is also amphoteric. 834:, an M−OH bending mode can be observed. For example, in it occurs at 1065 cm.
