Among `Al_(2)O_(3),SiO_(2),P_(2)O_(5) and SO_(3)` the correct order of acid strength is :-

A

`SO_(2) lt P_(2)O_(3) lt SiO_(2) lt Al_(2)O_(3)`

B

`Al_(2)O_(3) lt SiO_(2) lt P_(2)O_(3) lt SO_(2)`

C

`Al_(2)O_(3) lt SiO_(2) lt SO_(2) lt P_(2)O_(3)`

D

`SiO_(2) lt SO_(2) lt Al_(2)O_(3) lt P_(2)O_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B

Oxide of Al is amphoteric. `SO_(2)` is more acidic than `P_(2)O_(3)`. Therefore, correct order of acidic character is `Al_(2)O_(3) lt SiO_(2) lt P_(2)O_(3) lt SO_(2)`.
