Which of the following oxides is not expected to react with sodium hydroxide ?

A

`B_(2)O_(3)`

B

`CaO`

C

`SiO_(2)`

D

`BaO`

Text Solution

Verified by Experts

The correct Answer is:
B
Sodium hydroxide, NaOH, being a strong alkali neveneact with a basic oxide (compound). Among the given options, `B_(2)O_(3)` and Beo are amphoteric oxides `, SiO_(2)` is an acidic and `CaO` is a basic oxide. Therefore, NaOH does not react with CaO.
