Oxid Ion

Oxide-ion conducting ceramic materials have received considerable attention because of their potential applications in solid oxide fuel cells, oxygen separation membranes, and gas sensors.

Since hydroxide ion is the strongest base that can persist in water, the oxide ion reacts quantitatively with water to generate hydroxide ions. This is an example the leveling property of very strong bases. As predicted by the generalized solubility rules, only those metal oxides of the nonacidic and feebly acidic cation dissolve in water.

Oxide always has a 2− charge, so with three oxide ions, we have a total negative charge of 6−. This means that the two cobalt ions have to contribute 6+, which for …

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.

This movement is a result of thermally-activated hopping of the oxygen ions, moving from crystal lattice site to crystal lattice site, with a superimposed drift in the direction of the electric field. The ionic conductivity is consequently strongly temperature dependent,
