Which one of the following is an amphoteric oxide?

A$$Na_{2}O$$
B$$SO_{2}$$
C$$B_{2}O_{3}$$
D$$\mathrm{Z}\mathrm{n}\mathrm{O}$$
Correct Answer

Solution

$$\mathrm Na_{2}O $$ and first group oxides are basic while non-metal oxides such as $$\mathrm SO_{2}$$ and $$B_{2}O_{3} $$ are acidic.
ZnO is amphoteric because it can reacts with acid as well as base to produce salt and $$\mathrm H_{2}O$$.
