Detailed Solution

Alumina, or dialuminum trioxide, is the chemical formula for Al2O3. It acts as an acid in this reaction.

Sodium hydroxide is abbreviated as NaOH. It’s a solid base. When a base reacts with an acid, the results are usually salt and water.

As a result, acid alumina combines with the base sodium hydroxide to generate salt named sodium aluminate (NaAlO2) and water in this reaction.

Al2O3 + 2NaOH → 2NaAlO2+ H2O
