A

`CO`

B

`SnO_(2)`

C

`ZnO`

D

`SiO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
1
CO is neutral towards litmus. `SnO_(2)` and `ZnO` are amphoteric as they form salts and water with acids and bases, `SiO_(2)` is acidic as it forms salts with bases. `SiO_(2)+2NaOH rarrNa_(2)SiO_(3)+H_(2)O`
