On passing `CO_(2)` into aqueous solution containing `NaAlO_(2)`:

A

`Al_(2)(CO_(3))_(3)` is formed

B

`Al(OH)_(3)` is precipitated

C

`Al_(2)O_(3)` is formed

D

collodial `Al(OH)_(3)` is formed

Text Solution

Verified by Experts

The correct Answer is:
B
`CO_(2)+H_(2)Oto H_(2)CO_(3) hArrCO_(3)^(2-)+2H^(+)`
`3CO_(3)^(2-)+3H_(2)O+2Al^(3+) to 2Al(OH)_(3) darr ("as weakly acidic")+3CO_(2)`
