For example, vanadium oxide (VO 2) is an amphoteric oxide, dissolving in acid to give the blue vanadyl ion, [VO] 2+, and in base to yield the yellow-brown hypovanadate ion, [V 4 O 9] 2−. Amphoterism among the main group oxides is primarily found with the metalloidal elements or their close neighbours.

The extraction of gallium from Bayer solutions with the commercial amidoxine resin Duolite ES-346 was studied. While the loading, selectivity and kinetics are quite favourable, the long-term performance of the resin hinges on the degradation of the amidoxime groups in acid media and by the build up of vanadium.
