Amphoteric oxides can undergo neutralization reactions with both strong acids and strong bases. Base — Periodic Table and Periodicity Chemistry Question
Question
Amphoteric oxides can undergo neutralization reactions with both strong acids and strong bases. Based on their positions in the periodic table and corresponding electronegativities, which of the following pairs contain ONLY amphoteric oxides?
Answer: A,B
💡 Solution & Explanation
Elements on the borderline between metals and non-metals (moderate electronegativity) form amphoteric oxides. Standard amphoteric oxides include $BeO, Al_2O_3, ZnO, SnO, SnO_2, PbO, PbO_2, Ga_2O_3$. Options C are strongly basic. Options D are neutral oxides.
