Real World
Aluminium oxide's amphoteric nature is exploited in the Bayer process used by Rio Tinto to extract aluminium — bauxite ore is dissolved in NaOH because Al₂O₃ reacts with both acids and bases.
Exam Focus
Write balanced equations for each oxide reacting with water — mark schemes frequently award separate marks for correct formulae and state symbols.
