Formula and explanation
Amphoteric oxide + strong base → salt + water Example: Al₂O₃ + 2NaOH + 3H₂O ightarrow 2Na[Al(OH)₄] (or written as 2NaAlO₂ + 4H₂O ) Explanation: Amphoteric oxides (e.g., Al₂O₃, ZnO ) exhibit acidic properties and can react with strong bases to form salts (e.g., aluminate, zincate) and water.
