In the following reaction, ZnO is respectively acting as a/an -
I. `ZnO n+ Na_(2)O to Na_(2)ZnO_(2)`
II. `ZnO + CO_(2) to ZnCO_(3)` .

A

acid and acid

B

base and acid

C

acid and base

D

base and base

Text Solution

Verified by Experts

The correct Answer is:
C
ZnO is an amphoteric oxide. In the first reaction , `Na_(2)O` is a basic oxide . Thus ZnO behave as an acidic oxide. However in the second reaction in the presence of acidic oxide `CO_(2)` , it acts as a basic oxide.
