Which oxide can react with both acids and bases?

Answer and explanation

Correct answer: Amphoteric oxide

The governing concept is amphoterism. An amphoteric oxide reacts with an acid as a base and with a strong base as an acid, so it can show both types of chemical behaviour. Aluminium oxide and zinc oxide are common examples; ZnO + 2HCl → ZnCl2 + H2O, and ZnO reacts with NaOH in alkaline solution. Hence option C is correct.
