Which of the following oxides reacts with HCl and NaOH ?

A

CaO

B

ZnO

C

`N_2O_5`

D

`CO_2`

Text Solution

Verified by Experts

The correct Answer is:
B
CaO is basic, `N_2O_5` and `CO_2` are acidic. However ZnO is amphoteric. Thus, ZnO reacts both with HCl and NaOH
`ZnO + 2HCl to ZnCl_2 + H_2O`
`ZnO + 2NaOH to Na_2ZnO_2 + H_2O`
