The metals which can produce amphoteric oxides are:
(a) sodium and aluminium.
(b) zinc and potassium.
(c) calcium and sodium.
(d) aluminium and zinc

Academic Chemistry NCERT Class 10

Correct answer: (d) aluminium and zinc.

Explanation: Aluminium and Zinc reacts with both acids and bases. Hence, these are amphoteric in nature. So, the oxides of these elements are amphoteric oxides.
