An oxide that reacts with BOTH acids and bases to give a salt and water is called
Aa basic oxide
Ban acidic oxide
Ca neutral oxide
Dan amphoteric oxide
Answer & Solution
Correct answer: D. an amphoteric oxide
1. Some metal oxides show both acidic and basic behaviour.
2. Aluminium oxide and zinc oxide react with acids AND with bases to form salt + water — such oxides are **amphoteric**.
3. e.g. Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O and Al₂O₃ + 2NaOH → 2NaAlO₂ + H₂O.
