WebChemical Properties of Aluminium Oxide. 1. Reaction with sodium hydroxide. Aluminium oxide reacts with sodium hydroxide to produce sodium aluminate and water. This reaction takes place at a temperature of 900-1100°C. Salt and water are obtained in this reaction in which aluminium oxide acts as an acid. Al2O3 + 2NaOH → 2NaAlO2 + H2O.
