Which of the following sets of oxides is amphoteric in nature?

A$$Al_{2}O_{3}, As_{2}O_{3}, ZnO$$
Correct Answer
B$$CO,NO,N_{2}O$$
CNa2O,MgO,BaO
DAll of the above

Solution

Substances that can donate and accept protons, such as water and bicarbonate ion, are amphoteric. The oxides and hydroxides of metals like beryllium, zinc, aluminum, arsenic, and lead are also amphoteric. Amphoteric oxides show acidic as well as basic properties. Oxides of sodium, magnesium and barium are basic. $$CO$$, $$N_2O$$ and $$NO$$ are neutral.
