Question

In the following reactions, ZnO is respectively acting as a/an
`(i) ZnO + Na_(2)O rarr Na_(2) ZnO_(2)`
`(ii) NzO + CO_(2) rarr ZnCO_(3)`
A. Acid and acid
B. Acid and base
C. Base and acid
D. Base and base

Answer 1

Correct Answer - B
In (i) , NzO acts as an acidic oxide because `Na_(2)O` is a basic oxide
In (ii), ZnO acts as a basic oxide because `CO_(2)` is an acidic oxide
Thus, ZnO is an amphoteric oxide.
