\nThe correct answer is A, Aluminium oxide.
\n<\/section>\n
\nOxides are classified as acidic, basic, neutral, or amphoteric based on their reaction with acids and bases.
\nAmphoteric oxides are oxides that exhibit both acidic and basic properties, meaning they can react with both acids and bases to form salts and water.
\nAluminium oxide (Al\u2082O\u2083) is a common example of an amphoteric oxide.
\nIt reacts with acids: Al\u2082O\u2083(s) + 6HCl(aq) \u2192 2AlCl\u2083(aq) + 3H\u2082O(l)
\nIt reacts with bases: Al\u2082O\u2083(s) + 2NaOH(aq) + 3H\u2082O(l) \u2192 2Na[Al(OH)\u2084](aq) (Sodium tetrahydroxoaluminate, also written as 2NaAlO\u2082 + 4H\u2082O or similar)
\nCalcium oxide (CaO), Sodium oxide (Na\u2082O), and Potassium oxide (K\u2082O) are typically basic oxides, reacting with acids but not bases (except perhaps very strong, concentrated bases in specific conditions not characteristic of amphoterism).
\n<\/section>\n
\nOther examples of amphoteric oxides include Zinc oxide (ZnO) and Lead(II) oxide (PbO). The amphoteric nature of oxides often relates to the position of the metal in the periodic table; elements like Aluminium, Zinc, and Lead are on the border between metals and nonmetals.
