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

A

`B_(2)O_(3)`

B

`CaO`

C

`SiO_(2)`

D

`BeO`

Text Solution

Verified by Experts

The correct Answer is:
B
Being amphoteric orr acidic in nature `B_(2)O,SiO_(2) and BeO` react with strong base NaOH and form salts.
`B_(2)O_(3)+6NaOH to underset("Sodium borate")(2Na_(3)BO_(3))+3H_(2)O`
`SiO_(2)+2NaOH to underset("Sodium silicate")(Na_(2)SiO_(3))+H_(2)O`
`BeO+2NaOH to underset("Sodium beryllate")(Na_(2)BeO_(2))+H_(2)O`
