Question

In the following reactions, ZnO is respectively acting as a/an:
$\left(a\right)ZnO+N{a}_{2}O\to N{a}_{2}Zn{O}_2$
$\left(b\right)ZnO+C{O}_2\to ZnC{O}_3$

• A. base and acid
• B. base and base
• C. acid and acid
• D. acid and base

Answer 1

The correct option is D acid and base

Although ZnO is an amphoteric oxide but in given reaction.
$\left(A\right)ZnO+N{a}_{2}O\to N{a}_{2}Zn{O}_2$
acid base salt
$\left(B\right)ZnO+C{O}_2\to ZnC{O}_3$
base acid salt
