Among `Al_(2)O_(3),SiO_(2),P_(2)O_(3)` and `SO_(2)` the correct order of acidic strength is:
A
`Al_(2)O_(3) lt SiO_(2) lt SO_(2) lt P_(2)O_(3)`
B
`SiO_(2) lt SO_(2) lt Al_(2)O_(3) lt P_(2)O_(3)`
C
`SO_(2) lt P_(2)O_(3) lt SiO_(2) lt Al_(2)O_(3)`
D
`Al_(2)O_(3) lt SiO_(2) lt P_(2)O_(3) lt SO_(2)`
Text Solution
Verified by Experts
The correct Answer is:
D
As the size increases the basic nature of oxides changes to acidic nature i.e., acidic nature increases. `SO_(2)underset("Acidic") (gt) P_(2)O_(3)gt underset("Weak acidic")(SiO_(2))gt underset("Amphoteric")(Al_(2)O_(3))` `SO_(2)` and `P_(2)O_(3)` are acidic as their corresponding acids `H_(2)SO_(3)` and `H_(3)PO_(3)` are strong acids.
